MONTREALA Quebec womans desperate online plea for a compatible stem-cell donor in her bid to fight cancer a second time is shedding light on the lack of minorities on official lists in Canada and abroad.

Mai Duong finds herself battling leukemia again and doctors say they would like to proceed with a transplant of bone marrow or cord blood stem cells within a month.

But Duong, 34, has discovered that locating the right person can be a needle-in-a-haystack challenge, particularly for those who are from a non-Caucasian background.

This is a global problem, Duong, who is of Vietnamese origin, said in an interview from her room at Montreals Maisonneuve-Rosemont Hospital.

We cant do a scavenger hunt every time someone has this type of problem.

Duong, who returned home a few days after being interviewed, said a recent bone marrow biopsy showed no signs of cancer. She will now begin four weeks of maintenance chemotherapy, which is given in lower doses to assist in prolonging a remission.

The mother of a 4-year-old girl, Duong successfully fought off acute leukemia in 2013 with chemotherapy. She had to terminate a 15-week pregnancy to undergo the treatment. Duong was in remission until a blood test revealed leukemia had returned this past May.

Seventy per cent of people who had that type of leukemia were just cured with chemotherapy, and unfortunately Im in the 30 per cent, she said.

The diagnosis and a lack of a match in her family have touched off a mad scramble to find a fellow Vietnamese donor. An online campaign has taken that hunt global.

I have cancer, I had a relapse, I dont have a bone marrow (donor) these are things I cannot change, Duong said. So I said, what can I do about it?

here is epidemiological evidence that links type B coxsackie virus (CVB) infection with heart disease, and research published on July 31st in PLOS Pathogens now suggests a mechanism by which early infection impairs the heart's ability to tolerate stress at later stages of life.

CVB infection is very common and affects mostly children. The symptoms range widely: over half of the infections are thought to be asymptomatic, the majority of children who get sick have only a mild fever, and a very small proportion get inflammation of the heart or brain. On the other hand, 70 -- 80% of patients with heart failure show signs of a previous CVB infection but have no history of viral heart disease, raising the possibility that even a mild earlier infection makes them more vulnerable to get heart disease later on.

To investigate this, researchers from San Diego State University, USA, led by Roberta Gottlieb and Ralph Feuer, first established a mouse model of mild juvenile CVB infection. Mice infected with a non-lethal dose of the virus shortly after birth did not develop any heart disease symptoms during the infection or into adulthood, but they had a predisposition to heart disease later in life.

Detailed analysis of the mice after infection showed that the virus does indeed target the heart and is found in cardiac stem cells. When comparing the numbers of cardiac stem cells in previously infected adult mice with uninfected ones, the researchers found significantly smaller numbers in the infected mice.

To test whether the childhood infection and stem cell depletion had any effect on the adult heart, the researchers exposed infected mice to two different types of cardiac stress. They treated some of the mice with a drug known to overstimulate the heart, and they challenged another group by making them swim for 90 minutes every day for 14 days. Following both treatments, the infected mice showed clear signs of early heart disease whereas uninfected controls showed little or no symptoms.

Analyzing the stressed mice in more detail, the researchers found that the hearts from previously infected mice had impaired ability to re-arrange their heart blood vessels and grow new ones. This process, called vascular remodeling, is critical for the heart to respond to changes in the environment, including stress.

As discussed in the article, important open questions remain. For example, does CVB infection affect cardiac stem cells at any age, or is there a vulnerable period in early childhood? It is also not clear whether other strains of CVB have similar properties to the one used here, which was isolated from a patient with heart disease.

Nonetheless, the researchers conclude that their results "support the hypothesis that a mild CVB3 infection early in development can impair the heart's ability to undergo physiologic remodeling, leading to heart disease later in life." They also suggest that "the subtle cardiac alterations might go undetected under normal circumstances but emerge in the setting of increased demand such as intense exercise or chronic high blood pressure."

Advances in stem cell research will provide enormous opportunities for both biological and future clinical applications. Basically, stem cells could replicate any other cells in the body, offering immense hope of curing Alzheimer's disease, repairing damaged spinal cords, treating kidney, liver and lung diseases and making damaged hearts whole. The potential for profit is staggering. Prof. Jinhui Chen from Indiana University in USA considered that this field of research still faces myriad biological, ethical, legal, political, and financial challenges. The eventual resolution of these conflicts will determine the success of the research and potentially the face of medicine in the future. The relevant study has been published in the Neural Regeneration Research (Vol. 9, No. 7, 2014).

SINGAPORE - Singapore's life-saving Bone Marrow Donor Programme celebrated its 100th donor and new patron, Minister for Law and Foreign Affairs K Shanmugam, on Thursday.

Get the full story from The Straits Times.

Here is the statement from the Bone Marrow Donor Programme:

The Bone Marrow Donor Programme (BMDP) celebrates 21 years of saving lives through an extraordinary gift of kindness and generosity as ordinary Singaporeans commit to helping a fellow human being.

As bone marrow transplants become the preferred treatment for a wide number of blood related diseases such as leukaemia and lymphoma, the new BMDP Patron, Minister K Shanmugam, Minister for Law and Foreign Affairs and MP for Nee Soon GRC gave an award to the 100th Singaporean bone marrow donor, Lim Yun Song a 27 year-old Engineer and NTU graduate. This was in recognition of the commitment he and all the other bone marrow donors have made in a purely voluntary capacity to give of themselves a priceless gift of bone marrow (blood stem cells) to save the life of a stranger.

The BMDP manages Singapore's only registry of bone marrow donors and can literally be the last chance of survival for patients with terminal blood-related illnesses. Sadly, though, the chance of finding a donor whose DNA profile is a match to the patient is an alarming 1 in 20,000. With Singapore's unique and rapidly changing demographic, it is more important than ever to recruit more volunteers to join the registry and make sure that each patient is given this last chance of survival.

In conjunction with the 21st anniversary and office inauguration, the BMDP shared a number of significant milestones achieved in recent months.

In addition to reaching the 100th local donor, the number of local donors identified as a patient match increased from 38 in 2012 to 73 last year and year-to-date 64 donors were called up for Confirmatory Typing.

In tandem, the number of volunteers actually going through to make their life-saving donation has increased from seven in the whole of 2013, to nine in the first half of this year with more scheduled.

Minister Shanmugam says, "Bone marrow donors are heroes. They are given a chance to help a fellow human being through a simple yet selfless act of kindness - and they take it. This opportunity is available to everyone but so few rise to the challenge and I hope that more young people - the future of Singapore - will be inspired by what we are seeing here today and will sign up as volunteer bone marrow donors. I'm honoured to join the BMDP as their Patron, and look forward to working with them to build our community of heroes".

MicroRNAs (miRNAs) play an important regulatory role in the self-renewal and differentiation of stem cells. Dr. Defeng Zou and co-workers from the First Affiliated Hospital of China Medical University, China focuses on the effect of miRNA overexpression on the differentiation of bone marrow-derived mesenchymal stem cells into neurons. In the study released on the Neural Regeneration Research (Vol. 9, No. 12, 2014), researchers used GeneChip technology to analyze the expression of miRNAs in bone marrow-derived mesenchymal stem cells, neural stem cells and neurons. They constructed a lentiviral vector overexpressing miR-124 and transfected it into bone marrow-derived mesenchymal stem cells. Intracellular expression levels of the neuronal early markers -III tubulin and microtubule-associated protein-2 were significantly increased, and apoptosis was reduced in transfected cells. After miR-124-transfected bone marrow-derived mesenchymal stem cells were transplanted into the injured rat spinal cord, a large number of cells positive for the neuronal marker neurofilament-200 were observed in the transplanted region. The Basso-Beattie-Bresnahan locomotion scores showed that the motor function of the hind limb of rats with spinal cord injury was substantially improved. These results suggest that miR-124 plays an important role in the differentiation of bone marrow-derived mesenchymal stem cells into neurons, providing novel strategies for enhancing the therapeutic efficacy of bone marrow-derived mesenchymal stem cell transplantation for spinal cord injury.

Supporters of a Brisbane mother-of-two who died while undergoing a controversial stem cell treatment in Russia say it did not cause her death, nor have others been discouraged from seeking it.

Kellie van Meurs suffered from a rare neurological disorder called stiff person syndrome, which causes progressive rigidity of the body and chronic pain.

She travelled to Moscow in late June to undergo an autologous haematopoietic stem cell transplant (HSCT) under the care of Dr Denis Fedorenko from the National Pirogov Medical Surgical Centre.

WEDNESDAY, July 23, 2014 (HealthDay News) -- Most blood cancer patients in the United States who need a bone marrow transplant can find an acceptable match through the National Marrow Donor Program, a new study has determined.

Depending on a patient's race or ethnic background, the study found that 66 percent to 97 percent of patients will have a suitably matched and available live donor on the registry.

Even hard-to-match ethnic groups can find a suitable donation thanks to banked stem cells drawn from umbilical cord-blood donations, said senior author Martin Maiers, director of bioinformatics research at the National Marrow Donor Program.

All told, for patients who are candidates for either bone marrow or cord-blood transplants, the likelihood of having a suitable match is as high as 91 to 99 percent, the study found.

"For almost all patients, there is some sort of product available for them," Maiers said.

The findings, said to represent the first attempt to accurately determine the successful-match rate of the bone marrow registry, are published July 24 in the New England Journal of Medicine.

Patients suffering from blood-related cancers such as leukemia or lymphoma need a stem cell transplant to help them survive their cancer treatment. The transplant is done after chemotherapy and radiation is complete.

Donation from a relative is the best option, but only about 30 percent of patients have such a donor available, researchers said in background notes. The majority must rely on the National Marrow Donor Program to match them with a live bone marrow donor or banked stem cells gathered from donated umbilical cord blood.

The National Marrow Donor Program has on hand 11 million potential bone marrow donors and 193,000 banked cord-blood donations. The number of transplants facilitated by the program has quadrupled, with nearly 6,000 transplants in 2012 compared with 1,500 a decade earlier.

Good Odds for Those Who Need Bone Marrow Donor, Study Finds

Stem cell agency President C. Randal Mills (left) and Chairman of the Board Jonathan Thomas.

Responding to his predecessor's ethically controversial departure, the president and chief executive of California's stem cell agency said Thursday he is taking legal steps to minimize conflicts of interests with those who have business before the agency.

C. Randal Mills said he will not take a job with any company funded by the California Institute for Regenerative Medicine for one year after he departs the agency. In addition, he also will not accept gifts or travel payments from any company, institution or person who gets agency funding.

Mills' action, announced at the agency's meeting in Millbrae, will be enforced with a legal agreement he will sign. His action comes less than a month after he replaced Alan Trounson as the agency chief. One week after his departure, CIRM-funded StemCells Inc. announced it had appointed Trounson to its board. StemCells Inc. had received an award of nearly $20 million from the agency to develop a therapy for Alzheimers disease.

While Trounson's appointment wasn't illegal, critics said it was unseemly for him to join a company that had received agency funding so soon after he left CIRM. An ethical controversy could harm the agency's chances of getting more funding from California voters, who gave the agency $3 billion with the passage of Proposition 71 in 2004.

Mills said the new rules apply only to himself, because of his central role at CIRM.

"This specifically addresses an issue where an individual in an organization has a disproportionate amount of power, and I want to make sure it's known that power will not be abused," Mills said.

Mills made the right decision, said Jeanne Loring, a CIRM-funded stem cell researcher at The Scripps Research Institute.

"There's a difference between what is legal and what is ethical," said Loring, who attended the meeting. "And he's going to be pushing the needle a lot more toward the ethical side without worrying whether he can get away with stuff."

John Simpson of Santa Monica-based Consumer Watchdog, who has often criticized CIRM for conflicts of interest, also praised the decision.

This news release is available in German.

The immune system has evolved to recognize and respond to threats to health, and to provide life-long memory that prevents recurrent disease. A detailed understanding of the mechanism underlying immunologic memory, however, has remained elusive. Since 2001, various lines of research have converged to support the hypothesis that the persistence of immune memory arises from a reservoir of immune cells with stem-cell-like potential. Until now, there was no conclusive evidence, largely because experiments could only be carried out on populations of cells. This first strict test of the stem cell hypothesis of immune memory was based on mapping the fates of individual T cells and their descendants over several generations.

That experimental capability was developed through a long-term collaboration, focused on clinical cell processing and purification, between researchers based in Munich and Seattle. Since 2009, the groups of Prof. Dirk Busch at the Technische Universitt Mnchen (TUM) and Prof. Stanley Riddell at the Fred Hutchinson Cancer Research Center have combined their technological and clinical expertise under the auspices of the TUM Institute for Advanced Study. The University of Heidelberg, the University of Dsseldorf, the Helmholtz Center Munich, the German Cancer Research Center (DKFZ), and the National Center for Infection Research (DZIF) also contributed to the present study.

Homing In On The "Stemness" of T Cells

After generating an immune response in laboratory animals, TUM researchers Patricia Graef and Veit Buchholz separated complex "killer" T cell populations enlisted to fight the immediate or recurring infection. Within these cell populations, they then identified subgroups and proceeded with a series of single-cell adoptive transfer experiments, in which the aftermath of immune responses could be analyzed in detail. Here the ability to identify and characterize the descendants of individual T cells through several generations was crucial.

The researchers first established that a high potential for expansion and differentiation in a defined subpopulation, called "central memory T cells," does not depend exclusively on any special source such as bone marrow, lymph nodes, or spleen. This supported but did not yet prove the idea that certain central memory T cells are, effectively, adult stem cells. Further experiments, using and comparing both memory T cells and so-called naive T cells that is, mature immune cells that have not yet encountered their antigen enabled the scientists to home in on stem-cell-like characteristics and eliminate other possible explanations.

Step by step, the results strengthened the case that the persistence of immune memory depends on the "stemness" of the subpopulation of T cells termed central memory T cells: Individual central memory T cells proved to be "multipotent," meaning that they can generate diverse types of offspring to fight an infection and to remember the antagonist. Further, these individual T cells self-renew into secondary memory T cells that are, again, multipotent at the single-cell level. And finally, individual descendants of secondary memory T cells are capable of fully restoring the capacity for a normal immune response.

Los Angeles, CA (PRWEB) July 22, 2014

MetroMD, one of the leading names in regenerative medicines in all of California and one of the greatest proponents of holistic health services, now brings a reason to rejoice for individuals long suffering from debilitating arthritis. As per a report published on March 6 2013, by The Journal of Bone and Joint Surgery on The US National Library of Medicine National Institutes of Health (Ref: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3748969/), on an average, around 500,000 revision of knee replacement surgeries were recorded in the US - with the prime reason being osteoarthritis in majority of these cases. And If Mr. Devin Stone, MetroMDs Operations Director is to be believed, the cumulative cost of the treatment is estimated to be around $50 billion every year.

The cost covers hospitals bills, doctors visits, medicine, etc and makes arthritic treatment, which often requires a repeat procedure, a hugely burdensome endeavor. But the fact is, even after spending so much of money, one is not sure about getting fully relieved from the agony that arthritis brings to ones life. Arthritis appears in many forms and the expresses itself as joint pain, stiffness and limited body movement in a patient, says Dr Alex Martin, MD, MetroMDs Director of Medicines. MetroMD, ensures that patients can put aside all these concerns and enjoy complete healing that only an advanced Stem cell therapy for arthritis can promise, says Dr. Martin highlighting the fact regarding how pocket-friendly the treatment is. One can regain a healthy knee, while retaining the health of his/her money bag now with MetroMDs stem cell therapy.

How does MetroMDs Stem cell therapy Work?

MetroMDs stem cell treatment process includes extraction of healthy bone marrow out of the patients body by experts and placing it in a centrifuge. After segregating various elements of blood, the stem cell is isolated and placed with cellular growth promoters (found in platelets). All of these are then inserted into the part of the body, ensuring a quicker tissue-based healing.

Mr. Devin Stone exuded confidence in mentioning that MetroMDs stem cell therapies come as a great alternative to invasive surgeries - making way for easier and quicker knee replacements and arthritic treatment.

Is the stem cell therapy safe?

Dr. Alex Martin says, If you are suffering from chronic joint paint due to arthritis, surgery is not anymore the only answer. Stem Cell Therapy can provide an amazing alternative, where your own cells are used to promote healing inside your body. Medicine has advanced significantly in the last 15 years and persistence with the techniques that were pioneered over two decades ago is illogical- and newer and less invasive procedures are the future of medicine.

Backed by the fact that stem cell treatment is a minimally invasive procedure requiring little or no hospitalization, Dr Martins and MetroMDs stance towards propagating stem cell therapy looks only logical. The procedure is legal and the therapy rendered by MetroMD is in compliance with CFR 21 part 1271 standards. Being a non surgical process, evidently, its the safest and totally side-effect free process.

Dr. Martin welcomes the residents of LA suffering from debilitating arthritic condition to consult an expert at its branches spread across in several parts of Los Angeles - and enjoy an improved quality of life.

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.

Were severely underrepresented in the international list. So its not even a local or a national problem; its a global problem, said Duong.

Duong is turning to Vancouver because of its large Asian population, and urging people to get tested. She needs a donor of Vietnamese or Filipino descent for a perfect match, and she needs to find them within six weeks or its unlikely shell survive.

For more information on how you can help Duong, visit her Facebook pageor websiteand get tested at OneMatch.ca.

Montreal woman pleading with B.C. residents to save her life

Washington No batteries required: Scientists are creating a biological pacemaker by injecting a gene into the hearts of sick pigs that changed ordinary cardiac cells into a special kind that induces a steady heartbeat.

The study, published Wednesday, is one step toward developing an alternative to electronic pacemakers that are implanted into 300,000 Americans each year.

There are people who desperately need a pacemaker but cant get one safely, said Dr. Eduardo Marban, director of the Cedars-Sinai Heart Institute in Los Angeles, who led the work. This development heralds a new era of gene therapy that one day might offer them an option.

Your heartbeat depends on a natural pacemaker, a small cluster of cells its about the size of a peppercorn, Marban said that generates electrical activity. Called the sinoatrial node, it acts like a metronome to keep the heart pulsing at 60 to 100 beats per minute or so, more when youre active. If that node quits working correctly, hooking the heart to an electronic pacemaker works very well for most people.

But about 2 percent of recipients develop an infection that requires the pacemaker to be removed for weeks until antibiotics wipe out the germs, Marban said. And some fetuses are at risk of stillbirth when their heartbeat falters, a condition called congenital heart block.

For more than a decade, teams of researchers have worked to create a biological alternative that might help those kinds of patients, trying such approaches as using stem cells to spur the growth of a new sinoatrial node.

Marbans newest attempt uses gene therapy to reprogram a small number of existing heart muscle cells so that they start looking and acting like natural pacemaker cells instead.

Because pigs hearts are so similar to human hearts, Marbans team studied the approach in 12 laboratory pigs with a defective heart rhythm.

They used a gene named TBX18 that plays a role in the embryonic development of the sinoatrial node. Working through a vein, they injected the gene into some of the pigs hearts in a spot that doesnt normally initiate heartbeats and tracked them for two weeks.

Two days later, treated pigs had faster heartbeats than control pigs who didnt receive the gene, the researchers reported in the journal Science Translational Medicine. That heart rate automatically fluctuated, faster during the day. The treated animals also became more active, without signs of side effects.

The HIV virus (yellow particles), seen on a white blood cell in this scanning electron micrograph.

Scientists have uncovered two new cases of HIV patients in whom the virus has become undetectable.

The two patients, both Australian men, became apparently HIV-free after receiving stem cells to treat cancer. They are still on antiretroviral therapy (ART) as a precaution, but those drugs alone could not be responsible for bringing the virus to such low levels, says David Cooper, director of the Kirby Institute at the University of New South Wales in Sydney, who led the discovery. A year ago, a different group of researchers had reported cases with a similar outcome.

Cooper presented details of the cases today at a press briefing in Melbourne, Australia, where delegates are convening for next week's 20th International AIDS Conference. The announcement came just a day after the news that at least six people heading to the conference died when a Malaysia Airlines flight was shot down in Ukraine.

Cooper began searching for patients who had been purged of the HIV virus after attending a presentation by a US team last year at a conference of the International AIDS Society in Kuala Lumpur. At that meeting, researchers from Brigham and Womens Hospital in Boston, Massachusetts, reported that two patients who had received stem-cell transplants were virus-free.

Cooper and his collaborators scanned the archives of St Vincents hospital in Sydney, one of the largest bone-marrow centres in Australia. We went back and looked whether we had transplanted [on] any HIV-positive patients, and found these two, says Cooper.

The first patient had received a bone-marrow transplant for non-Hodgkin's lymphoma in 2011. His replacement stem cells came from a donor who carried one copy of a gene thought to afford protection against the virus. The other had been treated for leukaemia in 2012.

Unfortunately, several months after the 'Boston' patients stopped taking ART, the virus returned. An infant born with HIV in Mississippi who received antiretroviral therapy soon after birth, then stopped it for more than three years, was thought to have been cured, but has had the virus rebound, too.

At the moment, there is only one person in the world who is still considered cured of HIV: Timothy Ray Brown, the 'Berlin patient', who received a bone-marrow transplant and has had no signs of the virus in his blood for six years without ART. The bone marrow received by the Berlin patient came from a donor who happened to have a natural genetic resistance to his strain of HIV.

The brain has a low renewable capacity for self-repair and generation of new functional neurons in the treatment of trauma, inflammation and cerebral diseases. Cytotherapy is one option to regenerate central nervous system that aim at replacing the functional depleted cells due to traumatic brain injury (TBI). Bone marrow mesenchymal stem cells (BMSCs) are also considered a candidate for cytotherapy because they can differentiate into neurons/nerve cells, pass across blood-brain barrier, migrate into the injured region, secrete neurotrophic factor, and provide microenvironment for neural regeneration. Prof. Mohammad Ali Khalili, Research and Clinical Center for Infertility, Shahid Sadoughi University of Medical Sciences, Iran and his team administered TBI rats 3106 BMSCs via the tail vein and found that the BMSCs transplanted via the tail vein promoted nerve cell regeneration in injured cerebral cortex, which supplement the lost nerve cells. Related results were published in Neural Regeneration Research (Vol. 9, No. 9, 2014).

Since Vet-Stems last training session with AZ Pet Vet in the summer of 2013 the number of pets diagnosed with arthritis has increased as much as an estimated 13% say industry sources. As many as 65% of dogs between the ages of 7 and 11 years old will be inflicted with some degree of arthritis. For certain specific breeds the percentage is as high as 70%, with an additional estimated 7% remaining undiagnosed. AZ Pet Vets Family of Animal Hospitals equips their veterinarians with a complete package of services to help diagnose and treat dogs that are suffering pain or inflammation from osteoarthritis or polyarthritis. Stem cell therapy is one of these services, most commonly used to help decrease inflammation, help with the pain of osteo or polyarthritis, as well as other joint or ligament issues, and muscle injuries.

Vet-Stems Corey Orava, DVM will be leading a series of daily training sessions which include a RACE (Registry of Approved Continuing Education from the American Association of Veterinary State Boards) approved credentialing course, and the ability to consult on potential stem cell therapy cases with current patients of AZ Pet Vets Family of Animal Hospitals. Each of these sessions will help veterinarians and their staff to learn the ins and outs of stem cell therapy, as well as benefit from a hands-on experience to bring the best care to their patients and pet owners. Under the mentorship of Dr. Orava all of the 17 AZ Pet Vet Animal Hospitals will have the potential to collect fat and inject stem cells on qualifying pet patients.

AZ Pet Vet is a family of 17 animal hospitals with one vision: to provide the best comprehensive care for their highly valued patients. Whether it be routine wellness, or other type of medical care, AZ Pet Vet provides loving care and treatment for pets. As animal lovers and pet owners, they understand the connection owners have with your pet. The doctors and staff at each hospital strive to build a long term relationship with their client families and their pets, always making recommendations in the pets best health interest. The AZ Pet Vet Family of Animal Hospitals offer complete veterinary care from wellness, to vaccines, spays and neuters, dental, surgical and now regenerative medicine. Their animal hospital locations can be easily found at http://www.arizonapetvet.com/.

Since its formation in 2002, Vet-Stem, Inc. has endeavored to improve the lives of animals through regenerative medicine. As the first company in the United States to provide an adipose-derived stem cell service to veterinarians for their patients, Vet-Stem pioneered the use of regenerative stem cells for horses, dogs, cats, and some exotics. In 2004 the first horse was treated with Vet-Stem Regenerative Cell Therapy for a tendon injury that would normally have been career ending. Ten years later Vet-Stem celebrated its 10,000th animal treated, and the success of establishing stem cell therapy as a proven regenerative medicine for certain inflammatory, degenerative, and arthritic diseases. As animal advocates, veterinarians, veterinary technicians, and cell biologists, the team at Vet-Stem tasks themselves with the responsibility of discovering, refining, and bringing to market innovative medical therapies that utilize the bodys own healing and regenerative cells.

Experts say a $15 million trial to explore stem cells from cord blood for treating autism is premature.

A team at Duke University in Durham, North Carolina, is set to launch a $40 million clinical trial to explore stem cells from umbilical cord blood as a treatment for autism. But experts caution that the trial is premature.

A $15 million grant from the Marcus Foundation, a philanthropic funding organization based in Atlanta, will bankroll the first two years of the five-year trial, which also plans to test stem cell therapy for stroke and cerebral palsy. The autism arm of the trial aims to enroll 390 children and adults.

Joanne Kurtzberg, the trials lead investigator, has extensive experience studying the effectiveness of cord blood transplants for treating various disorders, such as leukemia and sickle cell anemia. Most recently, she showed that cord blood transplants can improve the odds of survival for babies deprived of oxygen at birth. A randomized trial of the approach for this condition is underway.

To really sort out if [stem] cells can treat these children, we need to do randomized, controlled trials that are well designed and well controlled, and thats what we intend to do, says Kurtzberg, professor of pediatrics and pathology at Duke. We firmly believe we should be moving ahead in the clinic.

Early animal studies have shown that stem cells isolated from umbilical cord blood can stimulate cells in the spinal cord to regrow their myelin layers, and in doing so help restore connections with surrounding cells. Autism is thought to result from impaired connectivity in the brain. Because of this, some groups of children with the disorder may benefit from a stem cell transplant, Kurtzberg says.

But others are skeptical of the approach. Autism is a complex disorder with many possible causes. Also, its unclear how stem cells derived from cord blood can improve connections in the brain. Given these important caveats, its too soon to conduct a test of this scale and investment, some experts say.

Its probably premature to run large trials without evidence that they have a therapeutic effect that [we] understand, cautions Arnold Kriegstein, director of the Broad Center of Regenerative Medicine and Stem Cell Research at the University of California, San Francisco.

Pilot trials In June, Kurtzberg launched the first phase of the trial, with 20 children between 2 and 5 years of age. Her team plans to infuse the children with a single dose of their own cord blood cells, banked at birth and preserved by freezing.
