How saving their baby teeth could help save children’s lives

Yorkshire (PRWEB UK) 21 January 2014

Ongoing worldwide research is consistently proving that stem cells will be a cornerstone of medical treatments in the future. Already, literally thousands of stem cell therapies for a host of dangerous and life-threatening conditions have already been successfully performed, and specialists agree that many newly discovered treatments are just around the corner.

Stem cells are biological cell types found in multicellular organisms like mammals, and that, of course, includes us. The incredible thing about stem cells is that they are able to divide and change into other types of cell, and this is what gives them their unique ability to repair, or even replace, cells that have been damaged by disease or injury.

The potential for the health of younger and future generations is enormous.

Although stem cells are found in many different parts of our body, it is the stem cells found in our childrens teeth that are most precious in terms of their potential to safeguard health. While an inevitable crystallisation process makes adult teeth useless for stem cell therapies, first teeth and young wisdom teeth contain tooth pulp in perfect condition to provide useable stem cells. Whats more, children naturally lose 12 milk teeth over a 5-year period, and this means plenty of chances to collect the teeth most likely to be suitable for harvesting stem cells. The other big advantage of childrens teeth is that they fall out naturally, and that makes recovering the teeth a pain-free, risk-free and non-invasive process.

Today, scientists have the expertise and technologies to safely extract and store stem cells taken from baby teeth and wisdom teeth. Crucially, storing a persons stem cells for possible use in their own future medical treatment means that compatibility or finding the right match wont ever be an issue. This is one of the key factors that has given rise to people storing their own childrens cells as a way of protecting them against a future illnesses or conditions. Having access to a childs stem cells makes any future treatment far more likely to succeed, an extremely encouraging situation given that scientists are regularly discovering more and more conditions they can treat using stem cells.

So, what about the specific illnesses and conditions that tooth stem cells can be used to treat?

Scientists already know that stem cells within tooth pulp have the ability to develop into a wide range of tissues, including skin, nerve, muscle, fat, cartilage and tendon. This amazing versatility has huge and positive implications for medical uses of tooth stem cells, and thats why almost everyone has a vested interest in this medical breakthrough, from young adults, parents and expectant parents right through to those who might one day want a family.

Stem cell therapy has already enabled practitioners to grow skin, tracheas and corneas, as well as repair human hearts. Even more excitingly, it is now widely agreed that future stem cell therapies will allow medical practitioners to tackle a host of injuries, illnesses and heredity conditions. Among them, these are likely to include Type 1 diabetes; neuronal degenerative disorders like Alzheimers, Parkinsons and Huntingtons disease; cardiovascular disease; paralysis due to spinal cord injury; liver disease, strokes; heart attacks and joint repair. Stem cells can also help to repair the bodys immune system and, under the right conditions, can even be used to form organs, bone and other tissue.

BioEden have a UK team that has been right at the very heart of the science surrounding the extraction and storage of tooth cells in fact they are one of the worlds leading authorities on it.

Intranasal stem cell therapy may one day treat brain disorders

Image: Jim Kopp

Many diseases of the central nervous system involve the death of neuronsso, theoretically, the replacement of dead cells should improve symptoms of degenerative disorders such as Parkinson's, Huntington's, amyotrophic lateral sclerosis (ALS) and Alzheimer's, as well as stroke and brain tumors. Stem cell therapy may do just that even though evidence of its effectiveness is mixed.

In any cell transplant procedure, the host organin this case, the brainmay reject its new additions. Further, it is unclear whether grafted cells can truly integrate into complex neural circuitry. Finally, current procedures require invasive surgical implantation, which can be expensive and risky. The surgery can cause neural inflammation, and the implanted cells may quickly die.

Intranasal administration may address at least some of these issues. Most important, it eliminates the need for surgery. Further, some research suggests that stem cells delivered intranasally are smartthey do not spread through the brain indiscriminately but instead target damaged cells.

Although it is difficult to predict when medical practice will adopt stem cell therapy for the brain, animal studies have produced some promising results. In a rat model of Parkinson's, for example, treatment with intranasal stem cells appeared to improve motor function and slow the neurological deterioration associated with the disease.

Arizona Pain Stem Cell Institute Now Offering PRP Therapy for Joint Arthritis Relief

Phoenix, AZ (PRWEB) January 08, 2014

The top Phoenix stem cell clinic in the Valley, Arizona Pain Stem Cell Institute, is now offering PRP therapy for joint arthritis relief. Platelet rich plasma therapy offers the potential for relieving the pain from knee, hip, shoulder and spinal arthritis. For more information and scheduling with the Board Certified Phoenix pain management doctors, call (602) 507-6550.

Platelet rich plasma therapy, known as PRP therapy, involves a simple blood draw. The blood is then spun in a centrifuge, which then concentrates platelets and growth factors for immediate injection into the arthritic joint. The PRP therapy then acts as an attractant for the body's stem cells.

Recent published studies have shown that PRP therapy offers significant pain relief for arthritic knees and helps preserve existing cartilage. One to three injections may be necessary to obtain optimal results, which are performed as an outpatient and entail minimal risk.

In addition to PRP therapy, the Arizona Pain Stem Cell Institute offers several other regenerative medicine treatments for both joint and spinal arthritis. This includes bone marrow and fat derived stem cell injections along with amniotic stem cell rich injections. These injections are offered for patients as part of numerous clinical research studies.

The stem cell injection studies are enrolling now at the Institute. The studies are industry subsidized, with the procedures performed by the Board Certified pain management physicians.

The Arizona Pain Stem Cell Institute is part of Arizona Pain Specialists. With 5 locations accepting over 50 insurances, the pain clinics offer comprehensive treatment options for patients with both simple and complicated pain conditions.

Call (602) 507-6550 for more information and scheduling.

Stem cell transplant problem solved, UCSD-led study says

(This is my blog post about the embryonic stem cell study. For my news article about the study, go here.)

Genetically modified human embryonic stem cells can solve one of the toughest problems facing embryonic stem cell therapy, immune rejection of transplanted cells, may have been solved, according to a UC San Diego-led research team.

The cells can be made invisible to the immune system by genetically modifying them to make two immune-suppressing chemicals, according to a study performed in mice given a human immune system. Immune functioning in the rest of the animal remains active. The immune protection also applies to differentiated cells derived from the stem cells.

If the approach works in people, patients receiving transplanted tissue or organs made from embryonic stem cells wouldn't have to take harsh immune-suppressing drugs, said Yang Xu, a UCSD professor of biology. The method also may prevent immune rejection of tissues grown from other types of stem cells.

These arehumanized laboratory mice that contain a functional human immune system. Such mice have been used for years; a UCSD research team developed a model with a stronger immune response to test their immune-suppressing tissues. / Zhili Rong, UCSD

Researchers placed genes in the stem cells to produce the two chemicals, CTLA4-lg and PD-L1, naturally made in the body. The humanized immune systems of the mice accepted transplants of cells engineered to make the chemicals. The researchers transplanted cardiomyocytes and fibroblasts derived from the engineered stem cells. Transplants derived from regular embryonic stem cells were rejected.

The study was published online Thursday in the journal Cell Stem Cell. Its findings will have to be confirmed for safety and effectiveness in more animal studies before human trials can be considered, which will take years. The mouse model itself was "optimized" for the study to more faithfully reflect the human immune system than other immune models, the study said.

Xu said a further study is being considered in monkeys, a large animal model considered to better reflect human biology than mice.

Embryonic stem cells are being tested along with many other kinds of stem cells to replace diseased or destroyed body parts, such as spinal cord segments and insulin-producing beta cells in the pancreas. All of these cells have advantages and drawbacks. Immune rejection, along with a tendency to form tumors, are two big drawbacks to embryonic stem cells.

San Diego-based ViaCyte is preparing to test a therapy with beta cells within a year. The company encapsulates them in a permeable barrier that allows insulin to diffuse out but prevents the immune system from entering. However, that approach won't worth with transplants that must integrate into the body, such as spinal cord tissue. So a way of turning off the immune system just in those cells is an attractive idea.

The study was published online Thursday in the journal Cell Stem Cell. Its findings will have to be confirmed for safety and effectiveness before human trials can be considered, which will take years.

Three scientists given the paper for comment had mixed reactions. While they praised the works scientific prowess, two said genetically engineering the transplanted cells could cause serious side effects that might preclude their use.

The researchers employed a clever strategy to use the immune systems natural regulatory systems, said Mitchell Kronenberg, president of the La Jolla Institute for Allergy & Immunology.

This is an especially promising approach, because it avoids the toxic side effects of the drugs now used to suppress the rejection response, and therefore this is an important step forward in showing the feasibility of using human embryonic stem cells from unrelated donors, Kronenberg said.

More skeptical were Jeanne Loring, a stem cell researcher at The Scripps Research Institute, and Craig M. Walsh, associate director of the Institute for Immunology at UC Irvine.

Embryonic stem cell rejection problem fixed, study says

Stem cell therapy breakthrough

Human embryonic stem cells have the capacity to differentiate into a variety of cell types, making them a valuable source of transplantable tissue for the treatment of numerous diseases, such as Parkinson's disease and diabetes.

But theres one major issue: Embryonic stem cells are often rejected by the human immune system.

Now, researchers from the University of California San Diego may have found an effective way to prevent this rejection in humans. Utilizing a novel humanized mouse model, the scientists have revealed a unique combination of immune suppressing molecules that stop the immune system from attacking the injected stem cells without shutting the system down completely.

This discovery could ultimately help resolve some of the major problems currently limiting the use of embryonic stem cells for certain conditions, paving the way for the development of more effective human stem cell therapies.

This is a generic way of immune suppression, so it could potentially be applied not just for stem cells therapies, but for organ transplants as well, Yang Xu, a professor of biology at UC San Diego and lead author of the study, told FoxNews.com. It can be very broad.

Embryonic stem cells are different from the other cells in a patients body, making them allogenic. This means the immune system will recognize them as foreign agents and attack them.

One way of overcoming this rejection problem is to give patients immunosuppressant drugs, which suppress the entire immune system. While short term use of immunosuppressants has been successful for many organ transplants, embryonic stem cell therapies for chronic diseases require long term use of these drugs which can often be very toxic and increase the risk of cancer.

In order for the patient to really use this therapy, they have to decide: Do they want a lifelong use of immunosuppressant drugs, or are they willing to live with the symptoms of their disease, Xu said.

To figure out a way of bypassing this issue, researchers needed a relevant model that could closely mimic the human immune systems response to embryonic stem cell transplantation. To do this, they took immune deficient lab mice and grafted them with human fetal thymus tissues and hematopoietic stem cells derived from the fetal liver.

Essentially, this created a highly specialized mouse model with very robust T cells capable of effectively rejecting foreign embryonic stem cells just like human T cells.

FEMA Search and Rescue Canine Receives Stem Cell Therapy So He Can Continue to Save Lives

Poway, CA (PRWEB) January 02, 2014

Phizer is a seven year old black lab belonging to Ohio Task Force 1 that recently had stem cell therapy by Vet-Stem, Inc. Phizer was brought to Cleveland Road Animal Hospital for a limp in his right hind. Dr. Chad Bailey recommended stem cell therapy. Both Vet-Stem and Cleveland Road Animal Hospital value the working dog and offered their services pro-bono in hopes that Phizers stem cell therapy would permit him to continue to provide search and rescue service.

Phizer is one of only five search and rescue canines owned by Ohio Task Force 1, one of 28 Task Forces across the US that make up the FEMA Urban Search and Rescue System. Phizer is trained to find living victims who may be trapped under collapsed buildings. He is unique because he is certified to work with more than one handler meaning that he can be used on more missions. If one of his handlers is not available the other may be. Phizer is trained to cover obstacles and treacherous terrain, climb metal ladders and investigate acres of terrain quickly and efficiently. These skills came in handy when Phizer was assigned to a mission recovering victims from hurricane Sandy.

Handlers Maureen May and Deana Hudgins noticed an intermittent limp in Phizers right rear leg when he first started moving, but got better with exercise. Although the limp was not preventing Phizer from his job, he was started on pain medicine, joint supplements and taken for exams to the local veterinarian. His radiology report showed signs consistent with mild degenerative joint disease in addition to another injury. Deana and Dr. Bailey started Phizer on injectable treatments, laser therapy, and discussed stem cells.

Since Phizers stem cell therapy used his own stem cells, a small portion of fat was collected and sent to Vet-Stems lab in California. Within 48 hrs the doses of stem cells were ready for injection by Dr. Bailey. Stem cells are regenerative cells that can differentiate into many tissue types and reduce pain and inflammation thus helping to restore range of motion and regenerate tendon, ligament and joint tissues (http://www.vet-stem.com/science). For Phizer this means that all of the issues identified in his exams may be helped with one therapy.

About Vet-Stem, Inc. Vet-Stem, Inc. was formed in 2002 to bring regenerative medicine to the veterinary profession. The privately held company is working to develop therapies in veterinary medicine that apply regenerative technologies while utilizing the natural healing properties inherent in all animals. As the first company in the United States to provide an adipose-derived stem cell service to veterinarians for their patients, Vet-Stem, Inc. pioneered the use of regenerative stem cells in veterinary medicine. The company holds exclusive licenses to over 50 patents including world-wide veterinary rights for use of adipose derived stem cells. In the last decade over 10,000 animals have been treated using Vet-Stem, Inc.s services, and Vet-Stem is actively investigating stem cell therapy for immune-mediated and inflammatory disease, as well as organ disease and failure.

Plantar Fasciitis Now Being Treated With Stem Cells

Plantar fasciitis, a chronic pain condition involving the sole of the foot, is now being treated using regenerative medicine like stem cell therapy, and offering the first form of real relief for many sufferers.

Plantar fasciitis affects millions of Americans, and is a condition in which the plantar fascia the thick tissue covering the sole of the foot is inflamed, causing severe pain on the bottom of the foot, and impeding activities such as running and walking.

The plantar fascia tissue is what connects the heel bone to the toes, thus creating the arch of the foot.

Traditional treatments for the debilitating injury have offered some relief in recent years through the use of physical therapy, NSAIDS, and steroid injections. However, these types of pain relief develop slowly over time, and are not an effective way to truly treat the problem. Stem cell therapy is going beyond these typical treatments, treating the root cause of the issue, and are often able to alleviate pain more quickly and with longer-lasting results.

Clinics in Arizona and California are just two examples of offices now offering stem cell injections of adult bone marrow and both fat- and amniotic-derived materials. Board certified pain management doctors at the Arizona Pain Stem Cell Institute, in Phoenix, and TeleHealth, in southern California, are giving patients suffering from the condition a low risk, outpatient alternative to corrective surgery.

Many other U.S. states now have pain treatment centers offering the plantar fasciitis stem cell therapy, as well.

Stem cells tested to repair hearts

Dr. Aidan R. Raney performs a checkup on heart attack patient Mark Athens, 52, on Tuesday, Dec. 17, at Scripps Green Hospital in La Jolla. Athens received a stem cell treatment to help his heart recover as part of a clinical trial to determine the treatments safety and effectiveness.

A new stem cell treatment may help heart attack patients do something once thought medically impossible regenerate dead heart muscle.

Scripps Health in La Jolla is one of three centers testing the therapy from Capricor, a Los Angeles biotech company. The cardiac stem cells are meant to boost the hearts natural ability to perform minor repairs. If it works, scars should shrink and functional heart muscle should grow.

Capricor gets the cells from donor hearts, grows them into the amount needed for treatment, then sends them to doctors taking part in what is called the Allstar trial. Doctors inject the cells into the coronary artery, where they are expected to migrate to the heart and encourage muscle regrowth.

The trial has successfully completed Phase 1, which mainly evaluates safety. On Dec. 17, Capricor said it had received permission to begin Phase 2, which will examine efficacy in about 300 patients who will get the treatment or a placebo. More information can be found at clinicaltrials.gov under the identifier NCT01458405.

The Allstar trial is funded with a $19.7 million disease team grant from the California Institute for Regenerative Medicine, or CIRM, the states stem cell agency.

This is a highly significant announcement for us at CIRM as its the first time weve funded a therapy into a Phase 2 clinical trial, Chairman Jonathan Thomas said in a Dec. 23 statement.

About 600,000 Americans die of heart disease annually, making it the leading cause of death, according to the Centers for Disease Control and Prevention in Atlanta. Even those surviving may be left permanently impaired, if the heart is severely damaged. These are the patients Capricor seeks to help.

Mark Athens received Capricors treatment on Sept. 25, about a month after having a moderate heart attack. The Encinitas resident was the last treated under Phase 1, said Scripps cardiologist Richard Schatz, who performed the procedure. It will take about six months to know whether the treatment worked, Schatz said.

Unlike many trials, Phase 1 was not placebo-controlled, so Athens knows he got the therapy. He appeared cheerful, smiling and bantering with his examining doctor during a Dec. 17 checkup at Scripps Green Hospital.

Gene therapy for human skin disease produces long-term benefits

PUBLIC RELEASE DATE:

26-Dec-2013

Contact: Mary Beth O'Leary moleary@cell.com 617-397-2802 Cell Press

Stem cell-based gene therapy holds promise for the treatment of devastating genetic skin diseases, but the long-term clinical outcomes of this approach have been unclear. In a study online December 26th in the ISSCR's journal Stem Cell Reports, published by Cell Press, researchers evaluated a patient with a genetic skin disorder known as epidermolysis bullosa (EB) nearly seven years after he had undergone a gene therapy procedure as part of a clinical trial. The study revealed that a small number of skin stem cells transplanted into the patient's legs were sufficient to restore normal skin function, without causing any adverse side effects.

"These findings pave the way for the future safe use of epidermal stem cells for combined cell and gene therapy of epidermolysis bullosa and other genetic skin diseases," says senior study author Michele De Luca of the University of Modena and Reggio Emilia.

EB is a painful condition that causes the skin to be very fragile and to blister easily, and it can also cause life-threatening infections. Because there is no cure for the disease, current treatment strategies focus on relieving symptoms. To evaluate stem cell-based gene therapy as a potential treatment, De Luca and his colleagues previously launched a phase I/II clinical trial at the University of Modena and recruited an EB patient named Claudio. The researchers took skin stem cells from Claudio's palm, corrected the genetic defect in these cells, and then transplanted them into Claudio's upper legs.

In the new study, De Luca and his team found that this treatment resulted in long-term restoration of normal skin function. Nearly seven years later, Claudio's upper legs looked normal and did not show signs of blisters, and there was no evidence of tumor development. Remarkably, a small number of transplanted stem cells was sufficient for long-lasting skin regeneration.

Even though Claudio's skin had undergone about 80 cycles of renewal during this time period, the transplanted stem cells still retained molecular features of palm skin cells and did not adopt features of leg skin cells. "This finding suggests that adult stem cells primarily regenerate the tissue in which they normally reside, with little plasticity to regenerate other tissues," De Luca says. "This calls into question the supposed plasticity of adult stem cells and highlights the need to carefully chose the right type of stem cell for therapeutic tissue regeneration."
