“Latest Stem Cells News”

Scientists at the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa have discovered a powerful new way to stimulate muscle regeneration, paving the way for new treatments for debilitating conditions such as muscular dystrophy.

The research, to be published in the June 5 issue of Cell Stem Cell, shows for the first time that a protein called Wnt7a increases the number of stem cells in muscle tissue, leading to accelerated growth and repair of skeletal muscle.

“This discovery shows us that by targeting stem cells to boost their numbers, we can improve the body’s ability to repair muscle tissue,” said senior author Dr. Michael Rudnicki. Dr. Rudnicki is the Scientific Director of Canada’s Stem Cell Network and a Senior Scientist at OHRI and Director of OHRI’s Sprott Centre for Stem Cell Research, as well as a Professor of Medicine at the University of Ottawa.

Stem cells give rise to every tissue and organ in the body. Satellite stem cells are specialized muscle stem cells that live in adult skeletal muscle tissue and have the ability to both replicate and differentiate into various types of muscle cells. Dr. Rudnicki’s team found that the Wnt7a protein, when introduced into mouse muscle tissue, significantly increased the population of these satellite stem cells and fueled the regeneration process, creating bigger and stronger muscles. Muscle tissue mass was increased by nearly 20 per cent in the study.

“Our findings point the way to the development of new therapeutic treatment for muscular diseases such as muscular dystrophy, sarcopenia and muscle wasting conditions resulting from extended hospital stays and surgeries,” said Dr. Rudnicki.

James Eilert went on a 20-mile bike ride the other day! Why is that amazing?

Because18 months ago, the thought of getting on a bicycle was too much exertion for the Michigan native. In 2006, at the young age of 34, James suffered a major heart attack, which damaged his heart muscle.

The heart damage left James fatigued, exhausted and short of breath. It was increasingly difficult to meet the demands of his job as an automotive engineer. He was gasping for breath and sweating all the time. His ejection fraction (EF) had sunk to 20-25%. Feeling depressed, James had given up hope of ever improving his quality of life. However, hope was restored when James found Vescell ™ adult stem cell therapy on the internet.

“I was in Class III congestive heart failure and had given up, but the amount of research and patient success stories I found on Vescell™ gave me new hope. I contacted them immediately,” James said.

On November 14, 2007, James flew to Bangkok, Thailand and received 41 million of his own stem cells via catheter to heal his ailing heart muscle. James exclaimed, “I didn’t feel a thing, it was just a simple catheterization!”

James raved about his experience and the care he received in Bangkok, “I have never been so well cared for in all my years going in and out of multiple hospitals for congestive heart failure. The doctors really listened to me and gave me confidence that they were my partners in improving my heart.”

After the treatment, James was thrilled with the results of the Vescell ™. “I had an echocardiogram only 2 weeks after my stem cell therapy and my completely dead apex was beating again. I was shocked and ecstatic at the same time.”

Since then, James has continued to improve and 18 months after treatment, he says, “I can do anything, the sky is the limit. I am now in Class I heart failure. My ejection fraction is at 50% and my doctors have lifted all restrictions.”

Today, James devotes his spare time to help other patients, as a patient volunteer, “I shudder to think how my life would have turned out if I hadn’t found the Vescell website. I was lucky. I want others to get the same second chance that I had.”

James is one of more than 500 patients who have had the Vescell ™ treatment. VesCell™ harnesses and enhances stem cells’ unique abilities, enabling the patient’s own body to heal itself.

Sierra Fedelem may look like any other 20-month-old, but her parents are doing everything they can to make sure her life is just like that of any other healthy human being.
Stem cell research has stirred quite the controversy in the United States, and though the current administration’s recent policy reversal on the issue could open the markets to treatments and commercialization, it’s still an option unavailable for American patients, like Sierra, unless they’re willing to travel across the world.

“The first time the neurologist said, ‘No, you don’t realize it, she’s never going to be able to walk, talk and see, and she’s always going to be at the mental level of a 4-month-old’,” Rosetta Fedelem said. “We were just shocked.”
The Fedelems hadn’t realized the extent of the brain damage Sierra suffered during birth.

“We said ‘We’re not going to stop, we’re going to start doing as much as you can for her’,” Rosetta said. “So we started praying and researching.”
Their research landed them in China, where Sierra received several treatments of adult stem cells extracted from somebody else’s umbilical cord. Adult stem cells differ from embryonic stem cells, in that they can be retrieved from adult organs or tissue.

While leading U.S. experts say the possibilities are far-reaching, the quality of overseas studies remains uncertain.
“It’s very hard to tell which is a good place, and which is not,” Texas A&M Health Science Center College of Medicine Institute for Regenerative Medicine Director Dr. Darwin Prockup said. “But of course, patients get to be desperate, and you can’t blame them for trying.”

Dr. Prockup said better adult stem cell treatments in the United States are coming. In March, President Barack Obama signed an executive order, reversing Bush administration policy, to allow scientists to continue stem cell research on ongoing projects. The results of the research will determine when the United States will open its doors to treatment.
“Of course there’s always danger with any therapy, so you have to be very careful, there’s always a risk-benefit you have to weigh carefully,” Prockup said. “That’s done in good medical centers. That’s why we’re a little slower.”

The Fedelems said they did weigh the pros and cons.
“I don’t accept new things easily, but when there’s enough evidence of results, I’m willing to try them,” Jason said. “And that’s exactly what happened here.”

In the three weeks they’ve been back from China, Sierra can sit up on her own for a few seconds, do an army crawl, and stand up for more than twice the amount of time she could before. Plus, her parents say she’s more alert and vocal.
Rosetta and Jason say they want Sierra to be able to walk, talk and see.

“Now we don’t know exactly which of those goals she’ll reach,” Rosetta said. “Our goal is, as parents, to push her to achieve her greatest potential, whatever that is. We’ll love her no matter what.”
The Fedelems said they spent more than$23,000 on treatments in China, but they raised $45,000. The rest of the funds went to a hyperbaric chamber, and other treatments Sierra will receive in Florida in two weeks.

Dr. Prockup said the institute will be working on four clinical trials. By the end of the year he expects they’ll begin one with adult stem cell research for treatment on knee cartilage repair. The institute also plans to conduct stem cell research on diabetes, heart disease and strokes.

“You can make liver. You can make pancreas. You can make bone. Therefore you can make neuro cells. You can make heart cells,” said Dr. Robert Carpenter
Yes, he said make a liver make a heart. From what? Stem cells from your teeth.

“We recently discovered that adult stem cells that don’t have the controversy related to it like embryonic cells have the ability to regenerate and treat a number of illnesses and injuries,” Carpenter said.
Stem cells are being studied to affect other disease like diabetes, kidney problems; liver problems even Parkinson’s disease. It’s in human clinical trials, and it is expected to be available within the next decade. Stem cells from teeth are proving much better than those from even bone marrow.

“With dental stem cells, since they are closely linked to bone and cartilage. It is easy to manipulate these immature cells into cartilage. They’ve actually in the laboratory, have made an exact human ACL,” said Carpenter.Baby teeth have the most viable cells.

“Stem cells in teeth particularly deciduous teeth or wisdom teeth and the follicles the surround wisdom teeth are very immature very plastic stem cells, plastic being the key word that are manipulable into a number of different tissue types,” the doctor said.
Wisdom teeth are also a great source of stem cells and that is why Abby DelGiacco is sending wisdom teeth to a lab to have them preserved with a program called Stemsave. Once her teeth are extracted, they are placed in a container, sealed in a temperature-controlled thermos and overnighted to a cryolab where her cells are preserved if she needs them.

“You never really know what is going to happen and never want to think about it but something you could awful disease and that is what this is for it is not only for degenerative neurological diseases. It is for tissue, bone muscle, tendons if I tear my ACL,” said DelGiacco.
Insurance doesn’t pay to store your stem cells there is a $590 set up laboratory fee and each year thereafter Abby will pay $100.

The cells are there if and when she needs them and studies are showing they maintain viability at least fifty years, probably more. And if you don’t have wisdom teeth left, don’t worry. All you need is one healthy tooth.

Concha Herrera Arroyo, from El Pais

The Cardiology department and the Area of Cell Therapy of Cordoba hospital Reina Sofia are carrying out clinical tests with patients who have suffered from a severe heart attack. With the implantation of the patient’s stem cells, the heart regenerates thus improving its wall motion, that is, its cardiac performance.

Indeed for the last four years, the Area of Cell Therapy of Cordoba hospital, led by haematologist Dr. Concha Herrera, has been implementing a therapy program with adult stem cells in patients with heart-related problems. However, this therapy is not a service the hospital offers yet. More specifically, at the end of 2007 the hospital ended a clinical test with patients who had suffered a severe myocardial infarction, that is, an obstruction of one of the main coronary arteries that stops the blood pump to the heart.

The test consisted of treating 30 people split into three groups of ten each at random. The first group was the control group, where patients received standard treatment for acute myocardial infarction; the second group was treated with stem cells directly implanted into the coronary artery affected using a catheterization; the third group was treated with a medicine called G-CSF, which makes cells move from the marrow to the blood, so that they get to the heart in a natural way, without having to do so through a catheter.

At the end of the test, the results revealed that the two groups treated without cells improved slightly, whereas patients transplanted with stem cells through the coronary arteries (vessels which bring the blood to the Herat muscle) did improve their ventricular function much more. This was interpreted as a significant decrease of the cardiac failure symptoms such as pain, fatigue and breathlessness when making small efforts.

Moreover, with this process it is possible to prevent some acute arrhythmias (change or irregularity in the rhythm of the heartbeat), which in many cases could result in the patient’s death. ‘However, it does not prevent a future heart attack’, Dr. Herrera assures.

In short, the stem cells transplanted from the marrow into the heart muscle have a double function: on the one hand they regenerate the heart cells, the cardiomiocites. In addition to this, they segregate a series of proangiogenic factors that produce blood vessels (angiogenesis) and can also produce the recruitment of stem cells that are in the myocardium itself.

A 300-euro bill has arrived for some couples that had stem cells taken from their child at birth three years ago. Sant’Anna has sent a bill to parents who decided to transport umbilical cord blood to Switzerland, which in Italy cannot be stored for personal use.

For the past year, the procedure is no longer free at Sant’Anna, but now the hospital is sending bills out to couples who had the procedure done in 2008 when the hospital was not yet making people pay and the operation was entirely free. Numerous couples in the past weeks have surprisingly received a bill from Sant’Anna and the complaints are rolling in, along with phone calls and e-mails, opinion columns in the newspapers and interviews on TV.

“Our first son was born in 2006,” said a couple of young parents who asked to remain anonymous. “We asked the hospital to keep the umbilical cord stem cells and send them to Switzerland where it is possible to pay for them to be stored for personal, future use. No one at Sant’Anna hospital told us that we would have had to pay for this service.”

A few weeks ago due to the upcoming birth of their second son, the couple returned to the hospital.

“We asked for the same service,” they explained, “and this time they asked us for a 300 euro payment in order to obtain the necessary certification to transport the blood to Switzerland. We accepted, despite the fact that 300 euros seemed excessive, because they only need a simple health document. We paid the bill, but recently we also received a second bill for the same amount and we discovered that the bill was for the birth of our first child 3 years ago.”

The same thing happened to about ten couples, which three years after receiving the same services from the hospital, were sent a bill by Sant’Anna Hospital. A 300-euro bill that was completely unexpected, since until the end of March 2008 the hospital had not set any price for the service.

Current laws in Italy do not allow people to store stem cells for personal use. Only free, voluntary, and anonymous donations of umbilical cord blood can be made, which are then made available to anyone who needs them, just like blood or organ donations.

“Voluntary donation is covered by the national health system,” said executives at the hospital through their press office. Donation for personal use is not covered because it is not part of the program. Orders from the healthcare ministry specify that public hospitals do not have to guarantee this service. The hospitals, like Sant’Anna, which make this service available, naturally have the right to charge patients for this service, since it is not covered by the national health system.”

At least until March 2008 there were no precise regulations on the matter.

“Regulations were set one year ago,” said heath-care officials, “and since then all of the couples are being informed that the cost of the service is 300 euros. This sum is needed in order to perform a detailed certification of the blood. This document is necessary to transport the stem cells across the border. The hospital must guarantee that the withdrawal was done in compliance with all of the regulations and that the sample is healthy, and that it has been collected and stored according to all regulations.”

However, Sant’Anna is sending out bills for children that were born before March 2008. “The couples knew that sooner or later they would receive a bill,” said hospital officials. “The sum was not established, but they were informed that this was not a free service.”
