A study published on September 25th in PLOS Pathogens reports a new primate model to test treatments that might cure HIV/AIDS and suggests answers to questions raised by the "Berlin patient", the only human thought to have been cured so far.

Being HIV-positive and having developed leukemia, the Berlin patient underwent irradiation followed by a bone-marrow transplant from a donor with a mutation that abolishes the function of the CCR5 gene. The gene codes for a protein that facilitates HIV entry into human cells, and the mutationin homozygous carriers who, like the donor, have two defective copiesprotects against HIV infection.

Several factors could have contributed to the cure of HIV/AIDS in the patient: (1) the ablation of blood and immune cells following irradiation killed all or many of the viral reservoir cells that are not eliminated by antiretroviral treatment (ART); (2) the CCR5 deletion mutation in the donor cells protected them and their progeny from HIV infection; (3) a "graft versus host" reaction occurred, where the transplanted cells and their progeny recognize the host cells as foreign and attacked and eliminated HIV-positive reservoir cells that survived the irradiation.

Guido Silvestri, from Emory University in Atlanta, USA, and colleagues investigated the relative contribution of the irradiation to eliminate the reservoir of HIV-infected cells. The scientists worked with the animal model of Simian Immunodeficiency Virus (SIV, a close relative of HIV that infects primates and causes a disease similar to AIDS) infection in rhesus macaques. Using a total of six monkeys (three of which served as controls and did not receive transplants) they performed, for the first time, hematopoietic stem cell transplantation in rhesus macaques infected with a chimeric simian/human immunodeficiency virus (SHIV) and treated with ART.

The researchers harvested hematopoetic stem cells from three macaques prior to infection (of all six animals) with SHIV. They also treated the macaques with ART to reduce viral load and mimic the situation in human HIV-infected patients on ART. They then exposed the three monkeys from which they had collected hematopietic stem cells to a high dose of radiation. This killed most of their existing blood and immune cells, including between 94 and 99% of their CD4-T cellsthe main target of HIV infectionin the blood. The irradiation was followed by transplantation of each monkey's own virus-free hematopoietic stem cells. The latter can regenerate the blood and immune cells, and did so in all three monkeys within 3 to 6 weeks. Because the transplanted cells are not from a different donor, no graft versus host disease would be expected, and none was observed.

After that time, the scientists stopped ART in all six monkeys. As expected, the virus rebounded rapidly in the control animals. Of the three transplanted animals, two also showed a rapid rebound. The third monkey developed kidney failure two weeks after ART was stopped and was euthanized. It still had undetectable levels of virus in the blood at that time, but post-mortem analysis showed low levels of viral DNA in a number of tissues, arguing that none of the three transplanted monkeys was cured.

The researchers acknowledge a number of limitations of the study, including the small number of monkeys, and the relatively short period of ART prior to irradiation and transplantation. Nonetheless, they say their study "supports the hypothesis that myeloablative total body irradiation can cause a significant decrease in the viral reservoir in blood cells, even though it was not sufficient to eliminate all reservoirs". Their results, they say, suggest that in the cure of the Berlin patient, "the use of the CCR5 mutant donor and/or the presence of graft versus host disease played a significant role".

Scientists at a Birmingham university have carried out research which could help find a cure for leukaemia.

The study by researchers at the University of Birmingham has been described as a key step in the process to understanding how the disease develops.

The research specifically investigated acute myeloid leukaemia and looked at the way blood cells behave in patients suffering from the illness.

University Professor Constanze Bonifer explained: Stem cells in the bone marrow generate billions of different blood cells each day. The process resembles a production line with genes acting as regulators to control each step of the blood formation.

Leukaemia arises when the DNA encoding regulators in the stem cells is changed by a mutation.

When a mutation occurs in the relevant regulator genes, the finely balanced order of the production line is disrupted with drastic consequences.

A chain reaction occurs, with the function of other regulators in the process being altered. The new cells no longer develop into normal blood cells, but leukemic cells that multiply and begin to take over the body.

The team, which carried out the research alongside experts from Newcastle University, used state-of-the-art technology to see how the cells could be manipulated to stop them from causing the disease.

Professor Olaf Heidenreich, of Newcastle University, said: One aberrant regulator reprograms thousands of genes. If targeting it can reverse the changes it is making to the cellular production line then it would ultimately point towards new avenues for a more precise treatment of leukaemia.

Knowing that the production line can be restored to normal function gives us real hope. Of course, that is much easier to do in the lab that it is in the human body.

The liver provides critical functions, such as ridding the body of toxins. Its failure can be deadly, and there are few options for fixing it. But scientists now report in the journal ACS Applied Materials & Interfaces a way to potentially inject stem cells from tonsils, a body part we don't need, to repair damaged livers all without surgery.

Byeongmoon Jeong and colleagues point out that currently, the only established method for treating liver failure or severe cases of liver disease is complete or partial transplantation. But the need is much greater than the number of available organs. Plus, surgery has inherent risks and a hefty price tag. A promising alternative in development is transplanting liver cells. One such approach involves using adult stem cells to make liver cells. Stem cells from bone marrow could be used, but they have limitations. Recently, scientists identified another source of adult stem cells that could be used for this purpose tonsils. Every year, thousands of surgeries are performed to remove tonsils, and the tissue is discarded. Now it could have a new purpose, but scientists needed a way to grow them on a 3-D scaffold that mimics real liver tissue. Jeong's team set out to do just that.

The researchers encapsulated tonsil-derived stem cells in a heat-sensitive liquid that turns into a gel at body temperature. They added substances called growth factors to encourage the stem cells to become liver cells. Then, they heated the combination up to a normal body temperature. The result was a 3-D, biodegradable gel that contained functioning liver cells. The researchers conclude that the same process has promise with some further tweaking for ideal conditions as an injectable tissue engineering technique to treat liver disease without surgery.

Tonsil stem cells could someday help repair liver damage without surgery

Published September 24, 2014

Scientists have found a new, non-surgical way to repair a damaged liver by using stem cells from tonsils, according to a new study.

The research, published in the journal ACS Applied Materials & Interfaces, involved tonsil-derived stem cells compressed into a heat-sensitive liquid that turned to biodegradable, 3-D gel at body temperature.

The scientists also added substances that encouraged the stem cells to become liver cells, according to a news release.

Similar alternatives have been discovered before, but the stem cells were taken from bone marrow and had limitations. With thousands of tonsillectomies performed each year, scientists are hopeful the discarded tissue may have a new purpose.

Researchers said the results of the study may create a less-expensive, non-invasive alternative to liver transplants.

When a child became ill, Jim Pattison was one of many who stepped up as a potential bone marrow donor.

Herald photo by Jodi Schellenberg

Jim Pattison was given two paperweights for his stem cell donation. He decided to become a donor in 1996, but was not a match until after 2010.

In 1996, Pattison was one of many who went on the bone marrow transplant list to help a one and a half year old child who was diagnosed with acute myeloid leukemia. The organizers of the donor drive expected maybe 50 people to show up and were shocked by the close to 400 who attended.

Sadly, the family didnt find a match and the girl died, but Pattison decided to stay on the registry.

They asked if I wanted to stay on and my answer was that if I would do it for Abigail I would do it for anybody, he said.

Throughout the years, Pattison was asked to test for more markers to see if he would be a match for someone else. He did his last test in 2010 and heard back a short time later with the news he was a match.

Pattison was chosen for a peripheral stem cell donation, which is different from a bone marrow transplant because it is less invasive.

I first went to where the stem cells are collected and had a physical, he explained. They sent me back with some drugs that I had to have injected here, that stimulate the stem cells to grow. I had four injections before I went.

They were looking to make sure I had a high enough level of stem cells to make the donation, he added.

Local man shares his story of stem cell donation

A teenager who gave stem cells to save the life of a stranger is backing a national campaign to find more donors.

In June, Celyn Evans, 17, became one of the youngest people in the UK to donate stem cells.

The Colchester Royal Grammar School sixth-form student is supporting Anthony Nolans Save a Life at 16 campaign.

The charity wants HMRC to include details about stem cell donation when it writes to teens with their National Insurance numbers ahead of their 16th birthday.

Celyn, of West Mersea, said: You often hear that young people are self absorbed and not interested in helping others, but I think thats wrong.

People just need to be made aware of how they can help. That is why I am supporting this campaign.

Celyn joined the bone marrow donor register last September when his brothers friend developed leukaemia.

He was not able to help the family friend, but in February, Anthony Nolan contacted him to say he was a possible match for another patient in need of a potentially life-saving transplant.

Celyn agreed to donate and, after a series of check-ups, made the donation in London in June.

Like 90 per cent of donors, he gave his stem cells through a simple, outpatient process similar to giving blood.

Celyn said: You often hear that young people are self absorbed and not interested in helping others, but I think thats wrong. People just need to be made aware of how they can help.

Its a very simple process, and I am surprised more people dont do it. But I think its just down to people knowing about it, which is where Anthony Nolans idea comes in.

Colchester: Selfless teen stem cell donor Celyn Evans backs campaign to find more young heroes

About three million Briton currently suffer osteoporosis which is affected by a number factors such as genes, a lack of exercise and poor diet and results in about 60,000 hip, 50,000 wrist and 120,000 spinal fractures every year, according to the National Osteoporosis Society, costing about 1.7 billion in health and social care.

Dr Ifty Ahmed, a researcher at Nottingham University, said his team wanted to provide a preventative treatment, strengthening the bones of those at risk before they suffered a fracture.

Speaking at the Regener8 conference on regenerative medicine, in Leeds last week, he said: Our aim would be to use screening to spot people who are at risk, then strengthen their bones before they get fractures.

It means that rather than waiting until people have a fall and break something, we would try to stop that ever happening, along with the consequences, loss of independence, surgery and secondary illnesses.

Previous attempts have been made to find ways of strengthening thinning bones but the difficulties of protecting the fragile stem cells has meant no such treatments have yet been developed.

Dr Ahmeds team hope to overcome this problem by puncturing the tiny hollow spheres of calcium phosphate allowing the stem cells to migrate inside them where they are protected.

The experimental treatment has not yet been trialled on humans.

It would involve extracting stem cells from a patients bone marrow and mixing them with the microspheres before injecting the paste into the vulnerable bones.

Dr Ahmed said: "If it works, this kind of treatment could be done in a day.

Until now the team have been funded by the Engineering and Physical Sciences Research Council but they are now looking for a commercial partner.

Two men who changed each others lives forever by being on the giving and receiving ends of a bone marrow transplant met for the first time today and had their first chance to say, Thank you, face-to-face.

Thank you so much, Joe Yannantuono, 33, said to his bone marrow donor, Justin Jenkins, 35, as he embraced him in a hug in a live, emotional meeting on Good Morning America.

Yannantuono, not very long ago, was waging a two-year long battle for his life against stage 4 lymphoma.

Toddler Meets Life-Saving Bone Marrow Donor

As his wife, Christine Buono, and his 4-year-old son, JJ Yannantuono, stood by his side, the family, from Staten Island, N.Y., got the unbelievable news that a man in Texas, a stranger, was a rare 10 for 10 genetic bone marrow match.

That stranger in Texas, Jenkins, of Dallas, had registered to be a bone marrow donor by chance 15 years ago when he was 21-years-old and donated blood because they were offering free snacks.

Soon after Jenkins was found to be a match, his stem cells were transported by airplane to New York and transplanted into Yannatuonos body in December 2012 at Memorial Sloan Kettering Cancer Center.

For more than one year after the successful transplant, Yannantuono had no idea whose cells he was now carrying in his body.

As Yannantuono was rebuilding his life, Jenkins life was thrown a tragic curveball. His mother, who raised him on her own and had been a big part of his donation journey, was killed in a car crash.

Bone Marrow Recipient Meets Donor Who Saved His Life

Investigators from the Institute for Research in Immunology and Cancer (IRIC) at the Universit de Montral have just published, in the journal Science, the announcement of the discovery of a new molecule, the first of its kind, which allows for the multiplication of stem cells in a unit of cord blood. Umbilical cord stem cells are used for transplants aimed at curing a number of blood-related diseases, including leukemia, myeloma and lymphoma. For many patients this therapy comprises a treatment of last resort.

Directed by Dr. Guy Sauvageau, principal investigator at IRIC and hematologist at the Maisonneuve-Rosemont Hospital, the research has the potential to multiply by 10 the number of cord blood units available for a transplant in humans. In addition, it will considerably reduce the complications associated with stem cell transplantation. And it will be particularly useful for non-Caucasian patients for whom compatible donors are difficult to identify.

A clinical study using this molecule, named UM171 in honor of the Universit de Montral, and a new type of bioreactor developed for stem culture in collaboration with the University of Toronto will be initiated in December 2014 at the Maisonneuve-Rosemont Hospital.

According to Dr. Guy Sauvageau, "This new molecule, combined with the new bioreactor technology, will allow thousands of patients around the world access to a safer stem cell transplant. Considering that many patients currently cannot benefit from a stem cell transplant for lack of matching donors, this discovery looks to be highly promising for the treatment of various types of cancer."

The Centre of Excellence for Cellular Therapy at the Maisonneuve-Rosemont Hospital will serve as production unit for these stem cells, and grafts will then be distributed to patients in Montreal, Quebec City and Vancouver for this first Canadian clinical study. Tangible results should be available one year later, that is, in December 2015. The significance of this new discovery is such that over time, conclusive clinical results could revolutionize the treatment of leukemia and other blood-related illnesses.

"These extraordinary advances result from the efforts of a remarkable team that includes extremely gifted students and postdoctoral investigators working in the IRIC laboratories," adds Dr. Guy Sauvageau. "Among them, the first authors of this publication: Iman Fars, doctoral student, and Jalila Chagraoui, research officer, along with the professionals in IRIC's medical chemistry core facility under the direction of Anne Marinier, who optimized the therapeutic properties of this new molecule."

Context

Umbilical cord blood from newborn children is an excellent source of hematopoietic stem cells for stem cell transplants, since their immune system is still immature and the stem cells have a lower probability of inducing an adverse immune reaction in the recipient.

Furthermore, it is not necessary for the immunological compatibility between donor and recipient to be perfect, unlike in a bone marrow transplant. However, in most cases the number of stem cells obtained from an umbilical cord is much too low for treating an adult, and its use is confined above all to the treatment of children. With the new molecule UM171 it will be possible to multiply stem cells in culture and to produce enough of them to treat adults, especially those who are not Caucasian, and who because of the lack of donors have limited access to transplants.

Collaborators from the Maisonneuve-Rosemont Hospital, the British Columbia Cancer Agency, the Ontario Cancer Institute and the Fred Hutchison Cancer Research Center also played an important role in evaluating the biological properties of this new molecule, and those from the University of Toronto in developing the bioreactor.

World Breakthrough: A New Molecule Allows for an Increase in Stem Cell Transplants

Written by Lidia Dinkova on September 17, 2014

A partnership between University of Miami researchers and a Georgia-based biomedical company this month made a new type of stem cell commercially available for bone regeneration and healing.

The marrow-isolated adult multi-lineage inducible cell, known as the MIAMI cell, is the result of 15 years of research by the University of Miami.

Since the stem cell was made commercially available, about 21 patients have been treated with a MIAMI cell infusion.

We are controlling the release to make sure it goes very smoothly, said Tracy S. Anderson, president and CEO of Vivex Biomedical Inc.

Vivex invested in the research and development of the cell and licensed the technology from UM for orthopedic use. The company has contracted with the universitys tissue bank to develop the cell for commercial use and pays an undisclosed royalty back to UM from sales.

Before the MIAMI cell goes to full national release in January 2015, Vivex is controlling the use of the cell.

I am going very slowly and selectively with the surgeons we are working with, Mr. Anderson said. Anytime you have a new product like this, you have to make sure that it goes smoothly.

Mr. Anderson didnt want to disclose revenue generated from the sale of the MIAMI cell, only saying that it has been significant.

So far, the MIAMI cell has been used in bone regeneration and healing in Utah, Florida, Georgia, Michigan, Illinois and Ohio.

UPDATE: After searching for more than two months for a bone marrow donor, Montreal leukemia patient Mai Duong has found a compatible cord blood donor. Its not the perfect solution, but doctors say its the next best thing.

It is not being released where the donor came from.

A woman has given birth to her child and has donated her babys umbilical cord to save another life, said Duong in a statement.

Thank you dear mommy, we cannot fathom the importance of your gesture. I am very moved and I profoundly thank you for what youve done.

Previous story:

VANCOUVER Mai Duong, 34, only has six weeksleft to get a life-saving stem cell or bone marrow transplant and shes pleading with the Lower Mainlands Asian population tosave her.

The mother of one was born and raised in Montreal. Shes had good health for most of her life, until she was diagnosed with leukemia in January 2013, while pregnant with her second child. Doctors told her she had to terminate the pregnancy she was at 15 weeks and start chemotherapy immediately.

Duongwent into remission, but ten months later the cancer was back. And this time it was more aggressive and chemotherapy wouldnt work, she was told. Instead, she needed stem cells or a bone marrow transplant.

Even though Im on the international registry list for donors, I did not have a match for the bone marrow. I was devastated when they told me that, she toldGlobal News.

It turns out the problem of finding a match, and a perfect one at that, is more common among those of Asian descent. In 2012, 2-year-old Jeremy Kong of San Francisco was diagnosed with leukemia and couldnt find a match until he went public. After doing so, he found a nine out of tenbone marrow donor match and underwent a transplant, but died a year later. Experts say Vietnamese, Chinese, Japanese, Korean, Filipino and other South Asian populations are behind Caucasians when it comes to donating blood and organs.

MISSISSAUGA Dorothy Vernon-Brown is on the search of her life.

When she was diagnosed with acute myaloid leukemia in August, 2013, the Mississauga mother said it was like a huge kick in the gut.

She underwent chemotherapy shortly after the diagnosis, which helped her into remission, but to survive, she has been told her only chance is a bone marrow transplant.

Bone marrow cells rescue patients from the lethal effect of chemotherapy, says Vernon-Browns oncologist, Dr. Mark Minden.

Since starting a relationship with Canadas stem cell and marrow network, One Match, Vernon-Browns search has come up empty.

Vernon-Brown says she is desperate: Recent tests show lower white blood cell counts in her blood an indication the cancer may be coming back.

But shes also worried about how few donors are from the black community. Vernon-Brown has been told her chance of finding a compatible donor are one in 10,000.

Genetics are key in finding potential stem cell and bone marrow donors says, One Match patient and transplant liaison, MaryLynn Pride said.

There is only a 25 per cent chance that even a sibling will be a match, says Pride. We have patients from all ethnic communities that are currently in need of a stem cell transplant.

Black Canadians makes up only 1 percent of all Canadians registered as potential donors, according to Pride.

Owen McMasters.

Owen McMasters, a 15-year-old student at Trinity High School, is facing a battle most kids his age will never face. Hes fighting leukemia again.

McMasters was first diagnosed in 2011. He managed to fight off the disease, but following a recent relapse, McMasters now needs a bone marrow transplant.

McMasters and his family have teamed up with Sharing Americas Marrow (SAM) to host bone marrow donor registration events at the Kornhauser Library courtyard on the University of Louisville Medical School campus Sept. 16 and 17 from 9 a.m.-3 p.m. and on the University of Louisville main campus in the Swain Student Activities Center Sept. 18 from 9 a.m.-3 p.m.

We spoke with Alex Kimura, director of Sharing Americas Marrow, about McMasters condition, the upcoming donor drive, and how signing up as a blood marrow donor can save a life.

THE VOICE-TRIBUNE: Please tell us about Owens struggle and how he is currently doing. Has he found a donor yet, and if not, is it possible he could find one at the upcoming drives?

ALEX KIMURA: Owen McMasters was diagnosed in November of 2011 when he was 12 years old with T-cell Acute Lymphoblastic Leukemia. Owen had nine months of intense chemotherapy and then had been managing his blood cancer until recently, when a relapse put him back in the hospital. Owen, a 15-year-old sophomore at Trinity High School in Louisville, is now going through chemotherapy again, but now his doctors at Kosair Childrens Hospital think that a bone marrow transplant is needed to cure him of his disease.

Siblings have a 25 percent chance of being a bone marrow donor match because matches are made based on DNA tissue types, but unfortunately neither of Owens two brothers are matches. A match for Owen or for one of the thousands of other blood cancer patients who are looking for a donor could be found at any of the upcoming bone marrow donor drives in the Louisville area. Donors who register are signing up to be a potential donor for ANY patient in need of transplant, including but not limited to Owen.

V-T: What part does healthy bone marrow play in fighting leukemia and other blood cancers?

KIMURA: Leukemia and other blood cancers signify that the bodys bone marrow is failing. The bone marrow is made up of red blood cells, white blood cells, and platelets, which are the cells that produce oxygen, fight infection, and help with clotting, respectively.

SAM and Trinity Teen Team Up for Bone Marrow Donor Drives

LOUISVILLE, KY (WAVE) - It could be the most important thing you do this week. A Louisville high school sophomore desperately needs a bone marrow match to win the fight he's battled for three years.

We first met Owen McMasters two and a half years ago when his family was fighting to get the chemotherapy drug they needed to put him into remission. Now they are looking for someone who literally might save his, or another child's, life.

Owen has always been willing to lend his smile and his story to events helping children with cancer, says his dad, surgical oncologist Dr. Kelly McMasters. "He's really tried to use this as a platform to help other kids."

In 2012, Owen shared his story when drug companies pulled the chemotherapy drug he needed. The McMasters say it was because it didn't cost much and not making drug companies much money. Eventually, a generic version was imported from India and Owen went into remission.

Dr. McMasters said he was, "a normal kid, went snowboarding, went fishing and did all kinds of normal kid things, started at Trinity High School, was having a great time."

Until his acute lymphoblastic leukemia - ALL - came back.

"A couple of weeks ago, he didn't feel well, came to the hospital and found out his cancer is back," said Dr. McMasters.

His treatment options are now extremely limited.

"Owen now needs a bone marrow transplant," Dr. McMasters said. "That's the only option for him."

Family members have been tested and ruled out. Now the McMasters are hoping someone, somewhere will get tested and be a match.

Louisville teen desperately searching for bone marrow match

(PRWEB UK) 11 September 2014

Without doubt the best stem cells are those found in the baby teeth of young children.

Why? Apart from their unique ability to morph and change into other stem cells, thus treating a far wider range of illnesses and conditions, mesenchymal stem cells can proliferate outside the body, and where children are concerned no tooth extraction is needed as they fall out naturally. Above all it is important to remember that the best type of cells are those which are young, and therefore have not been contaminated by a lifetime of use and exposure.

So does that mean for adults there is no hope for stem cell retrieval from their adult teeth and little chance of success if they are needed in stem cell therapy?

Not necessarily, says Mike Byrom, Chief Scientific Officer at specialist tooth stem cell bank, BioEden.

Stem cell therapy is not a black and white type of event. There are varying degrees of success based on many factors of which the capacity of the cells is one. The functional capacity of a 44 year old cell is not as good as that of a 6 year old but that does not mean that they have no value. Our requirements for storing material mean that the cells demonstrate acceptable growth rates, expected cellular morphology and growth characteristics which indicate their ability to differentiate into tissue specific lineage cell types. If the cells do not meet our minimum criteria for usefulness we will not store them.'

Aside from these tests we cannot make any specific guarantees about the cells usefulness. Adults should not be put off attempting to store their stem cells and can have faith that if we successfully complete the process of stem cell extraction then the cells are of high enough quality to be useful should they be required.

BioEden do not make any charge for the process of harvesting stem cells where no viable stem cells can be found.

Munich, Germany: A new study has revealed how stem cells work to improve lung function in acute respiratory distress syndrome (ARDS).

Previous studies have shown that stem cells can reduce lung inflammation and restore some function in ARDS, but experts are not sure how this occurs. The new study, which was presented at the European Respiratory Society's International Congress today (09 September 2014), brings us a step closer to understanding the mechanisms that occur within an injured lung.

ARDS is a life-threatening condition in which the efficiency of the lungs is severely reduced. It is caused by damage to the capillary wall either from illness or a physical injury, such as major trauma. ARDS is characterised by excessive and dysregulated inflammation in the lung and patients require mechanical ventilation in order to breathe.

Although inflammation is usually a method by which the body heals and copes with an infection, when the inflammation is dysregulated it can lead to severe damage. Immune cells known as macrophages can coordinate the inflammatory response by driving or suppressing inflammation, depending on the stimulation.

The researchers investigated whether stem cells can affect the stimulation of the macrophages and promote the state in which they will suppress the inflammation.

They tested this in an animal model using human bone marrow-derived stem cells. Mice were infected with live bacteria to induce acute pneumonia and model the condition of ARDS. The results showed that treatment with stem cells led to significant reductions in lung injury, inflammation and improved bacterial clearance. Importantly, when stem cells were given to animals that had their macrophages artificially removed, the protective effect was gone. This suggests that the macrophages are an important part of the beneficial effects of stem cells seen in this model of ARDS.

These results were further supported by experiments where stem cells were applied to human macrophages in samples of fluid taken from lungs of patients with ARDS. Again, the stem cells were able to promote the anti-inflammatory state in the human macrophage cells. The authors have identified several proteins, secreted by the stem cells, that would be responsible for this effect.

In early 2011, Barrington resident Joanne Sullivan started to notice she was feeling out of breath.

At that time, she didnt do anything about it, but in May, when walking up a hill in town required her to stop three times to catch her breath, she couldnt ignore it any longer.

She visited her doctor in May and was put right in the hospital. Almost within a day, she was diagnosed with myelofibrosis, a bone marrow cancer that blocks production of red blood cells.

After undergoing blood transfusions, she began to feel better but also was researching her condition.

Its something a lot of people can live with for a long time, she said.

However, Sullivans blood counts never stabilized, and she was getting blood transfusions every month. At 56, she decided she couldnt live being transfusion-dependent.

Her doctor at Mayo Clinic, Mrinal Patnaik, told her about stem cell donations and she didnt hesitate.

I just said, Lets go for it, she said.

When a related match could not be found, Patnaik, a consultant in the division of hematology and bone marrow transplant, turned to the marrow registry. He selected a 55-year-old man from Germany as Sullivans donor.

Her transplant was scheduled for Jan. 18, 2012, and went smoothly. As a matter of fact, she was back to work in May.

So, when teenagers receive their National Insurance number through the post, why not also include an invitation to join the Anthony Nolan bone marrow register, and give them a chance to save a life at 16?

Email your MP to ask them to support Anthony Nolan's plan

Stem cell donations can play a crucial role in the treatment of blood cancers such as leukaemia and non-Hodgkin's lymphoma. In the UK each year 2,000 people with blood cancer need a donation of healthy cells, and every single one of them depends on the kindness of a stranger. This is where the Anthony Nolan register comes in.

When a patient needs a lifesaving transplant, their medical team works with us to find a match.

Today there are over half a million people on our donor register. That number grew by 55,000 names last year.

But only six per cent of those donors are aged between 16 and 20, and we need many more in this age group to come forward. We know that young people are more likely to be chosen by doctors as donors for people with blood cancer.

This is why Anthony Nolan recruits young people from the age of 16 and why sending registration information with National Insurance numbers could be such an important move.

Similar measures have been taken before. The Driver and Vehicle Licensing Agency includes information on organ donation when it delivers new driving licences. This is an innovative way to get individuals to think about a small but significant commitment they can make to help others.

Young people such as Victoria Rathmill and Celyn Evans are ground-breakers, and should be applauded as pioneers. What they have done takes courage. But the point of being a pioneer is to forge a path that others will follow. Our proposal, a simple awareness-raising measure, will help a great many people. It won't even cost the taxpayer a penny, as all expenses will be paid by Anthony Nolan.

We already have over 530,000 incredible people on our register, which is an amazing achievement. Sadly, its not enough. If we are to find a match for every person who needs one, we urgently need more people in their teens and twenties to sign up in the fight against blood cancer. By taking on our proposal, the Government can make it easier for young people to do just that.

Patients have include elite athletes, celebrities, executives, students, manual laborers and senior citizens. In other words, every walk of life can benefit.

The procedures offered include stem cell therapy for arthritis, back pain, cartilage defects, tendonitis, migraines, fracture healing and ligament injuries. The procedures are often able to help patients avoid the need for surgery and provide excellent pain relief with increased function.

Said R3 CEO Bob Maguire, MBA, Dr. Raj is a highly respected, skilled and compassionate provider who is committed to providing cutting edge options to his patients. It can help them heal faster while achieving pain relief. Thats what R3 Centers of Excellence strive for and have been very successful with to date.

Several different types of regenerative medicine procedures are offered at the R3 Center of Excellence. Amniotic stem cell procedures have shown amazing benefits in small studies to date. The fluid is obtained from consenting donors after a scheduled c-section, with the material being processed at an FDA regulated lab. No fetal tissue is involved or embryonic stem cells.

Bone marrow aspirate stem cell therapy is also offered, with the same day procedure injecting the processed bone marrow into the problem area. A high concentration of stem cells and growth factors sparks an impressive healing process, which can often regenerate damaged tissue.

Platelet rich plasma therapy is also offered, which involves a simple blood draw from patients. Studies are beginning to show that the regenerative medicine procedures work well for helping patients avoid the need for joint replacement surgery and also assisting athletes to get back on the field faster than otherwise.

Beverly Hills Orthopedic Institute Becomes R3 Stem Cell Center of Excellence

CHILHOWIE, Va. You wouldnt think from seeing her smile and watching her run and play that there is anything wrong with 5-year-old Nevaeh Bruner of Chilhowie.

But shes lucky to be alive and faces a lengthy procedure that could be her only chance for survival.

Pam Troxel Buchanan, the little girls great aunt, and Donna Hamm, her great-great aunt, are taking care of Nevaeh and tear up just thinking about what this little girl has been through and what she faces in her fight to live.

She is a very strong little girl. I couldnt do it, said Buchanan.

Nevaeh has been diagnosed with aplastic anemia, a rare disease that causes a complete failure of production of all types of blood cells. As a result, the bone marrow contains large numbers of fat cells instead of the blood-producing cells that would normally be present. It is a potentially fatal blood disease in which there are not enough stem cells in the bone marrow or the stem cells have stopped working effectively.

Buchanan said that last November Nevaehs teacher at Chilhowie Elementary School noticed bruising on her body. She had shown no other symptoms of illness, Buchanan said, so her parents were advised to take her to Niswonger Childrens Hospital in Johnson City, Tennessee, where there is a St. Jude affiliate clinic.

Buchanan said they spent a month running tests and the doctors told Nevaehs parents that her blood count was so low that she would not have lived much longer had she not received treatment. The little girl, who was 4-years-old at the time, has undergone numerous procedures, including surgery, transfusions, chemotherapy and radiation. She is taking oral chemotherapy and having blood transfusions as needed, but she is being weaned off the chemo to undergo a bone marrow transplant.

The chemo is also causing her kidneys to malfunction, bringing her close to kidney failure, Buchanan said.

She will always be in stage two kidney disease, Buchanan said. She will have sensitive kidneys and have to live with that.

The only option at this point is a bone marrow transplant, Buchanan said. Two donor matches have been found and the procedure will take place at St. Jude in Memphis, Tennessee, at the end of this year or next spring, Buchanan said.

Human trials on the effectiveness of using adult stem cells in the fight against cornea transplant rejection could be under way within the next five years.

Corneal eye disease is the fourth most common cause of blindness in the world and affects more than 10 million people worldwide. New research from NUI Galway has found that transplant rejection rates could be reduced to as low as 10% by administering a stem cell grown from the bone marrow of adult donors.

Although 100,000 people worldwide undergo cornea transplants each year, about 30% are unsuccessful due to rejection by the patients own immune system.

An unhealthy cornea affects vision by scattering or distorting light and causing glare and blurred vision.

Corneal transplants are the most widely used treatments where the diseased or scarred cornea is replaced with healthy tissue from an organ donor.

Researchers from NUI Galways Regenerative Medicine Institute previously found that mesenchymal stem cells (MSC) release chemicals capable of adjusting the immune system balance in the body.

The cells can be readily obtained and grown from the bone marrow of adult donors and the finding led them to study their usefulness in combating cornea transplant rejection.

The teams lead scientist, Dr Oliver Treacy, said the model system they developed led to an increase in cells called regulatory T-cells, which dampen down inflammation, and a decrease in the number of natural killer cells, key players in the rejection process.

Consultant ophthalmologist at Galway University Hospital, Gerry Fahy, who was involved in the study, said corneal transplant rejection could result in blindness and was not uncommon in high-risk patients.

This important research presents a potentially new avenue of treatment to prevent transplant rejection and save vision in this vulnerable group of patients, said Mr Fahy.

Putnam Valley, NY. (Sept. 3, 2014) A team of researchers from Korea and Canada have found that transplantation of B10 cells (a stable immortalized human bone marrow derived mesenchymal stem cell line; B10 hMSC) directly into the bladder wall of mice modeled with spinal cord injury (SCI) helped inhibit the development of bladder fibrosis and improved bladder function by promoting the growth of smooth muscle cells in the bladder.

The study will be published in a future issue of Cell Transplantation and is currently freely available on-line as an unedited early e-pub at: http://www.ingentaconnect.com/content/cog/ct/pre-prints/content-CT-1227_Lee.

Spinal cord injury (SCI) can cause severe lower urinary tract dysfunction and conditions such as overactive bladder, urinary retention and increased bladder thickness and fibrosis. HMSCs, multipotent cells that can differentiate into a variety of cell types, including bone cells, cartilage cells, and fat cells, have been transplanted into injured spinal cords to help patients regain motor function.

In this study, mice receiving the B10 hMSCs injected directly into the bladder wall experienced improved bladder function while an untreated control group did not.

"Human MSCs can secrete growth factors," said study co-author Seung U. Kim of the Division of Neurology at the University of British Columbia Hospital, Vancouver, Canada. "In a previous study, we showed that B 10 cells secrete various growth factors including hepatocyte growth factor (HGF) and that HGF inhibits collagen deposits in bladder outlet obstructions in rats more than hMSCs alone. In this study, the SCI control group that did not receive B10 cells showed degenerated spinal neurons and did not recover. The B10-injected group appeared to have regenerated bladder smooth muscle cells."

Four weeks after the onset of SCI, the treatment group received the B10 cells transplanted directly into the bladder wall. To track the transplanted B10 cells via magnetic resonance imaging (MRI), the researchers labeled them with fluorescent magnetic particles.

"HGF plays an essential role in tissue regeneration and angiogenesis and acts as a potent antifibrotic agent," explained Kim.
