StemCell Therapy

Johannesburg, Mar 25 : Stem cells could repair damage in people with advanced heart disease, a new study has claimed.

According to researchers at a major US cardiology conference, patients with advanced heart disease who received an experimental stem cell therapy showed slightly improved heart function.

The clinical trial involved 92 patients, with an average age of 63, who were picked at random to get either a placebo or a series of injections of their own stem cells, taken from their bone marrow, into damaged areas of their hearts.

The patients all had chronic heart disease, along with either heart failure or angina, and their left ventricles were pumping at less than 45 percent of capacity.

All the participants in the study were ineligible for revascularisation surgery, such as coronary bypass to restore blood flow, because their heart disease was so advanced.

Those who received the stem cell therapy saw a small but significant boost in the heart's ability to pump blood, measuring the increase from the heart's main pumping chamber at 2.7 percent more than placebo patients.

Study authors described the trial as the largest to date to examine stem cell therapy as a route to repairing the heart in patients with chronic ischemic heart disease and left ventricular dysfunction.

"This is the kind of information we need in order to move forward with the clinical use of stem cell therapy," News24 quoted Emerson Perin, the lead investigator from Texas Heart Institute as saying.

Perin's research, which was conducted between 2009 and 2011 across five US sites, was presented at the annual American College of Cardiology Conference in Chicago.

Stem cell therapy `may repair heart damage`

ScienceDaily (Mar. 22, 2012) Researchers at the University of Bonn artificially derive brain stem cells directly from the connective tissue of mice.

Scientists at the Life & Brain Research Center at the University of Bonn, Germany, have succeeded in directly generating brain stem cells from the connective tissue cells of mice. These stem cells can reproduce and be converted into various types of brain cells. To date, only reprogramming in brain cells that were already fully developed or which had only a limited ability to divide was possible. The new reprogramming method presented by the Bonn scientists and submitted for publication in July 2011 now enables derivation of brain stem cells that are still immature and able to undergo practically unlimited division to be extracted from conventional body cells. The results have now been published in the current edition of the journal Cell Stem Cell.

The Japanese stem cell researcher Professor Shinya Yamanaka and his team produced stem cells from the connective tissue cells of mice for the first time in 2006; these cells can differentiate into all types of body cells. These induced pluripotent stem cells (iPS cells) develop via reprogramming into a type of embryonic stage. This result made the scientific community sit up and take notice. If as many stem cells as desired can be produced from conventional body cells, this holds great potential for medical developments and drug research. "Now a team of scientists from the University of Bonn has proven a variant for this method in a mouse model," report Dr. Frank Edenhofer and his team at the Institute of Reconstructive Neurobiology (Director: Dr. Oliver Brstle) of the University of Bonn. Also involved were the epileptologists and the Institute of Human Genetics of the University of Bonn, led by Dr. Markus Nthen, who is also a member of the German Center for Neurodegenerative Diseases.

Edenhofer and his co-workers Marc Thier, Philipp Wrsdrfer and Yenal B. Lakes used connective tissue cells from mice as a starting material. Just as Yamanaka did, they initiated the conversion with a combination of four genes. "We however deliberately targeted the production of neural stem cells or brain stem cells, not pluripotent iPS multipurpose cells," says Edenhofer. These cells are known as somatic or adult stem cells, which can develop into the cells typical of the nervous system, neurons, oligodendrocytes and astrocytes.

The gene "Oct4" is the central control factor

The gene "Oct4" is a crucial control factor. "First, it prepares the connective tissue cell for reprogramming, later, however, Oct4 appears to prevent destabilized cells from becoming brain stem cells" reports the Bonn stem cell researcher. While this factor is switched on during reprogramming of iPS cells over a longer period of time, the Bonn researchers activate the factor with special techniques for only a few days. "If this molecular switch is toggled over a limited period of time, the brain stem cells, which we refer to as induced neural stem cells (iNS cells), can be reached directly," said Edenhofer. "Oct4 activates the process, destabilizes the cells and clears them for the direct reprogramming. However, we still need to analyze the exact mechanism of the cellular conversion."

The scientists at the University of Bonn have thus found a new way to reprogram cells, which is considerably faster and also safer in comparison to the iPS cells and embryonic stem cells. "Since we cut down on the reprogramming of the cells via the embryonic stage, our method is about two to three times faster than the method used to produce iPS cells," stresses Edenhofer. Thus the work involved and the costs are also much lower. In addition, the novel Bonn method is associated with a dramatically lower risk of tumors. As compared to other approaches, the Bonn scientists' method stands out due to the production of neural cells that can be multiplied to a nearly unlimited degree.

Low risk of tumor and unlimited self renewal

A low risk of tumor formation is important because in the distant future, neural cells will replace defective cells of the nervous system. A vision of the various international scientific teams is to eventually create adult stem cells for example from skin or hair root cells, differentiate these further for therapeutic purposes, and then implant them in damaged areas. "But that is still a long way off," says Edenhofer. However, the scientists have a rather urgent need today for a simple way to obtain brain stem cells from the patient to use them to study various neurodegenerative diseases and test drugs in a Petri dish. "Our work could form the basis for providing practically unlimited quantities of the patient's own cells." The current study was initially conducted on mice. "We are now extremely eager to see whether these results can also be applied to humans," says the Bonn scientist.

A new shortcut for stem cell programming

A local toddler with a very rare disease has begun a long recovery in Penn State Hershey Childrens Hospital after chemotherapy and a stem cell transplant.

Chevy Hockenberry, the 23-month-old son of Lance Hockenberry and Melissa Johnson of Mercersburg, suffers from Hurlers syndrome, a rare inherited genetic disorder that if left untreated, causes death within five years.

People with Hurlers syndrome do not produce lysosomal alpha-L-iduronidase, an enzyme that helps break down long chains of sugar molecules. The long sugar chains build up in the body, damage internal organs and eventually lead to death.

The transplant

Chevy was diagnosed with Hurlers in January, but his symptoms started showing up long before that.

He was always sick, Johnson said by phone from Hershey. Chevy was always in and out of the hospital and had developed pneumonia and mild scoliosis.

Once he was diagnosed, the only treatment option for was a stem cell transplant.

Its not curable, Johnson said. But the stem cell transplant stops the progression.

The stem cells came from donated umbilical cords and Chevys parents because they are both carriers of Hurlers.

Chevy had multiple weeks of enzymes infusion followed by nine days of chemotherapy before the stem cell transplant.

CHICAGO (AFP) - Patients with advanced heart disease who received an experimental stem cell therapy showed slight improvements in blood pumping but no change in most of their symptoms, United States researchers said on Saturday.

Study authors described the trial as the largest to date to examine stem cell therapy as a route to repairing the heart in patients with chronic ischemic heart disease and left ventricular dysfunction.

Previous studies have established that the approach is safe in human patients, but none had examined how well it worked on a variety of heart ailments.

The clinical trial involved 92 patients, with an average age of 63, who were picked at random to get either a placebo or a series of injections of their own stem cells, taken from their bone marrow, into damaged areas of their hearts.

CHICAGO Cell therapy may present an option for patients with ischemic heart disease to use their own bone marrow cells to repair the damaged areas of their hearts, and may pave the way for future treatment options, according to the FOCUS trial, which will be presented as a late-breaking clinical trial March 24 at the 61st annual American College of Cardiology (ACC) scientific session.

This is the largest study to date to look at stem cell therapy, using a patient's own stem cells, to repair damaged areas of the heart in patients with chronic ischemic heart disease and left ventricular dysfunction. Researchers found that left ventricular ejection fraction (the percentage of blood leaving the heart's main pumping chamber) increased by a small but significant amount (2.7 percent) in patients who received stem cell therapy. The study also revealed that the improvement in ejection fraction correlated with the number of progenitor cells (CD34+ and CD133+) in the bone marrow; and this information will help in evaluating and designing future therapies and trials.

"FOCUS is an incredibly important trial, as it has informed the cell therapy community how to better treat this high-risk patient population, and allows us to enter into an exciting, next generation of stem cell therapy armed with more data," said study investigator Timothy D. Henry, MD, an interventional cardiologist at the Minneapolis Heart Institute (MHI) at Abbott Northwestern Hospital in Minneapolis and director of research with the Minneapolis Heart Institute Foundation.

This multicenter study was conducted by the Cardiovascular Cell Therapy Research Network (CCTRN), which is supported through a research grant from the National Institutes of Health's National, Heart, Lung and Blood Institute (NHLBI), with the goal to evaluate novel stem cell-based treatment strategies for individuals with cardiovascular disease.

FOCUS will be presented at ACC.12 by its lead investigator Emerson C. Perin, MD, PhD, director of clinical research for cardiovascular medicine at the Texas Heart Institute, one of the five sites in the CCTRN. The Minneapolis Heart Institute is another site of the five in the network, and a large number of CCTRN patients were enrolled in Minnesota.

For this study, which took place between April 2009 and April 2011, the five sites randomly selected 92 patients to receive stem cell treatment or placebo. The symptomatic patients, with an average age 63, all had chronic ischemic heart disease and an ejection fraction of less than 45 percent (baseline 34 percent) along with heart failure and/or angina and were no longer candidates for revascularization. "These patients had no other options, as medical management failed to improve their symptoms," explained the study's co-investigator Jay Traverse, MD, an interventionalist cardiologist at the Minneapolis Heart Institute at Abbott Northwestern Hospital and physician researcher with the Minneapolis Heart Institute Foundation.

Bone marrow was aspirated from the patients and processed to obtain just the mononuclear fraction of the marrow. In patients randomly selected to receive stem cell therapy, physicians inserted a catheter into the heart's left ventricle to inject 100 million stem cells in more than 15 sites that showed damage on the electromechanical mapping image of the heart.

"Studies such as these are able to be completed much faster because of the team approach of the network" said Sonia I. Skarlatos, PhD, NHBLI's deputy director of the division of cardiovascular sciences and program director of CCTRN.

Cell therapy using patient's own bone marrow may present option for heart disease

SATURDAY, March 24 (HealthDay News) -- An innovative approach using patients' own bone marrow cells to treat chronic heart failure came up short in terms of effectiveness, researchers report.

Use of stem cell therapy to repair the slow, steady damage done to heart muscle and improve heart function is safe, but has not been shown to improve most measures of heart function, the study authors said.

"For the measures we paid most attention to, we saw no effect, there is no question about that," said researcher Dr. Lemuel Moye, a professor of biostatistics at the University of Texas School of Public Health in Houston.

"Ultimately, this is going to pay off handsomely for individuals and for public health in general, but it's going to take years of work," Moye said. "We are the vanguard looking for new promising lines of research."

While the hoped-for results didn't materialize, there appeared to be a small improvement in some patients, he said. "When we looked at another commonly used measure of heart function called ejection fraction, or the strength of the heart's pumping, that's where all the action was," Moye noted.

It's hard to know which measures of heart function to look at, Moye explained. "We have had some difficulty with that," he said.

Future research will look at other measures of heart function, pay more attention to the characteristics of the cells that are injected and determine which cells are best, he added.

Cardiac cells and other types of specially prepared cells are available now that were not accessible when this study started in 2009, Moye pointed out.

The results of the trial, which was sponsored by the U.S. National Heart, Lung, and Blood Institute, were to be presented Saturday at the American College of Cardiology's annual meeting in Chicago. The report was also published online March 24 in the Journal of the American Medical Association.

For the study, Moye and colleagues worked with 92 patients, average age 63 and mostly male, who had heart failure with and without chest pain. They were randomly assigned to receive either an injection of 100 million bone marrow cells from their own bone marrow, or an inactive placebo. Patients in both groups also received aggressive medical therapy.

Shortly after a mouse embryo starts to form, some of its stem cells undergo a dramatic metabolic shift to enter the next stage of development, Seattle researchers report today. These stem cells start using and producing energy like cancer cells.

Julie Mathieu

A colony of human embryonic stem cells.

This discovery is published today in EMBO, the European Molecular Biology Organization journal.

These findings not only have implications for stem cell research and the study of how embryos grow and take shape, but also for cancer therapy, said the senior author of the study, Dr. Hannele Ruohola-Baker, University of Washington professor of biochemistry. The study was collaborative among several research labs in Seattle.

The metabolic transition they discovered occurs very early as the mouse embryo, barely more than a speck of dividing cells, implants in the mothers uterus. The change is driven by low oxygen conditions, Ruohola-Baker explained.

The researchers also saw a specific type of biochemical slowdown in the stem cells mitochondria the cells powerhouses. The phenomenon previously was associated with aging and disease. This was the first example of the same downshift controlling normal early embryonic development.

This downshift coincides with the time when the germ line, the keeper of the genome for the next generation, is set aside, Ruohola-Baker said.. Hence reduction of mitochondrial reactive oxygen species may be natures way to protect the future.

Embryonic stem cells are called pluripotent because they have the ability to renew themselves and have the potential to become any cell in the body. Self-sustaining and versatile are qualities necessary for the growth, repair and maintenance of the body and for regenerative medicine therapies.

Although they share these sought-after qualities, Pluripotent stem cells come in several flavors, Ruohola-Baker explained. They differ in subtle ways that expand or shrink their capacities as the raw living material from which animals are shaped.

Although they share these sought-after qualities, "Pluripotent stem cells come in several flavors," Ruohola-Baker explained. They differ in subtle ways that expand or shrink their capacities as the raw living material from which animals are shaped.

There's a big reason why the researchers wanted to understand the distinction between the stem cells that make up the inner cell mass of the free-floating mouse embryo, and those in the epiblast, or implantation stage. Mouse embryonic cells at the epiblast stage more closely resemble human embryonic stem cells -- and cancer cells.

Human stem cells and mouse epiblast stem cells have lower mitochondrial respiration activity than do earlier stage mouse stem cells. This reduction occurs despite the fact that the later stage stem cells have more mature mitochondria. The researchers confirmed that certain genes that control mitochondria are turned down during the transition from inner cells mass to epiblast cells.

Instead, the transitioning cells obtain their energy exclusively from breaking down a sugar, glucose. In contrast, the earlier stage mouse embryonic stem cells have more energy options, dynamically switching from mitochondrial respiration to glucose breakdown on demand.

Lancme will launch what it believes to be the latest "miracle" anti-aging product next month, with a rose stem cell-based cream.

Called Absolue L'Extrait, each jar of the cream contains two million rose stem cells, with the product suitable for people of all ages to be applied on the face, eye area, hands and chest.

Retailing at 320 for 50ml, the cream will launch in April across Europe, Asia and the Middle East, before reaching the US in June.

Absolue L'Extrait has been dubbed a "miracle cream" by the brand, which began investigating how plant stem cells act on human skin many years ago.

The rose, also the emblem of the French beauty giant, was a particular point of focus. Using a biotechnological cocooning procedure, scientists transformed a cell of the Lancme Rose into a rose stem cell.

"Once you put these rose stem cells in contact with the human stem cells, you have 63% more of these cells in the skin that stay at their optimum level, which is really a first," Youcef Nabi, president of Lancme International, told WWD March 22.

Other companies to have remarked on the benefits of rose stem cells include US skincare brand Dermelect, which last year launched the Dermelect Alpine Rose Stem Cell Skincare line, a range of treatments based on the Swiss Alpine Rose which uses rose stem cells to increase skin's resilience and boost epidermal rejuvenation.

Users of ChimerMarker, a short tandem repeat chimerism analysis software solution marketed by SoftGenetics, are reporting a significant reduction in the time required to analyze STRs in blood samples of patients who have undergone bone marrow transplants.

The tool automates the process of assessing the chimerism ratio the proportion of donor cells relative to the host patients own cells in post-transplant cases based on the presence of STRs that are unique to both the patient and the donor, Don Kristt, head of molecular pathology at the Rabin Medical Center in Israel, explained to BioInform this week.

According to SoftGenetics, the software can be used to monitor chimerism levels in allogeneic and autologous stem cell transplants or hematopoietic stem cell transplants; bone marrow transplants; and cord and peripheral blood stem cell transplant samples.

SoftGenetics partnered with Kristt to develop the software, which it released last March (BI 3/18/2011). The company later added a module for testing fetal samples for maternal cell contamination prior to performing genetic testing for cystic fibrosis or other diseases (BI 9/2/2011).

The software provides capabilities for genotyping and chimerism analysis and tools to automatically identify donor and recipient peaks in samples following bone marrow transplants. It also calculates percent chimerism and quality metrics for single donor or double donor cases.

Dawn Wagenknecht, who supervises the HLA-Vascular Biology Laboratory at Franciscan St. Francis Health, told BioInform this week that her team was able to reduce the time required to calculate the ratio of donor to recipient cells in blood samples by as much as 85 percent.

She explained that the team ran parallel analyses of 10 blood samples using both ChimerMarker and a manual approach that the lab had used prior to purchasing the software, which involved manually sorting data generated by capillary sequencing in Excel spreadsheets, and then calculating the ratios either on the sheet or using a hand calculator.

In addition to the time savings, ChimerMarker also simplifies the analysis process because all the steps of the workflow are in a single package, she said.

The software also maintains records of the donor sample and the patients blood before transplantation so that the results from subsequent tests after transplant can be compared to the initial samples, she said.

ANNAPOLIS, Md. (WJZ)One of the last search and rescue dogs from 9/11 lives here in Maryland. She was suffering from a painful condition until her owner took action with breakthrough technology.

Mary Bubala has the story.

Red is a search and rescue dog from Annapolis, but has traveled across the country. Her missions include Hurricane Katrina, the La Plata tornadoes and the Pentagon after 9/11.

They credit them with finding 70 percent of the human remains so that helped a whole lot of those families actually get closure, said Heather Roche, Reds owner.

Sept. 11 was Reds first search. Today shes one of the last 9/11 search and rescue dogs still alive.

She retired last summer due to severe arthritis.

It would be nice if her arthritis, if she felt better, that she could do those kinds of things that she misses, Reds owner said while fighting back tears. Alright I am going to cry.

Roche did some research and found an animal hospital in northern Virginia that uses breakthrough stem cell therapy to treat arthritis in dogs.

The Burke Animal Clinic is one of just a few across the country that use stem cell therapy.

The vet harvests 1 to 2 ounces of the dogs fatty tissue, activates the stem cells and then injects them back into the troubled areas.

Stem Cell Therapy Used To Treat 9/11 Search And Rescue Dog

POWAY, CA--(Marketwire -03/22/12)- Vet-Stem announced today the introduction of StemInsure. The StemInsure service provides banked stem cells that can be grown to supply a lifetime of stem cell therapy for dogs. One fat collection, in conjunction with another anesthetized procedure, gives access to a lifetime of stem cells.

Vet-Stem has trained over 3,500 veterinarians, provided stem cells for over 8,000 animals in the US and Canada and currently banks more than 25,000 doses for future therapeutic use. Many veterinarians and their clients have requested a method to collect and store stem cells when a dog is young, before it needs the regenerative cells for therapy. StemInsure was designed to meet this need.

A Vet-Stem credentialed veterinarian can collect as little as 5 grams of fat (about the size of a grape) from a dog or puppy during an anesthetized procedure. Many veterinarians and owners are electing to do this fat collection in conjunction with a spay or neuter. This small amount of fat is processed and stem cells are cryopreserved in Vet-Stem's state-of-the-art facility. The cells can be cultured in the future to provide enough stem cells to last for the lifetime of the dog. More information can be found at http://www.vet-stem.com/steminsure.php.

"Vet-Stem is pleased to provide StemInsure as a solution to the thousands of veterinarians and dog owners who recognize the value of Vet-Stem cell therapy. The ability to store the cells in conjunction with another procedure is a great way to ensure that the dog will have access to a lifetime of cell therapy while reducing the number of anesthetic events," said Dr. Bob Harman, DVM, MPVM, and CEO of Vet-Stem. Dr. Harman continued, "Currently, Vet-Stem Regenerative Cell Therapy is widely used to treat osteoarthritis, and tendon/ligament injuries. It is our expectation that the therapeutic use of adipose derived stem cells will continue to expand and add to the value of a lifetime supply of stem cells for dogs."

About Vet-Stem:In January of 2004, Vet-Stem introduced the first veterinary stem cell service in the United States. Since that time there has been rapid adoption of this technology for treatment of tendon, ligament, and joint injuries by the veterinary community. Studies have shown that mesenchymal stem cells can dramatically improve the healing of injuries and diseases that have had very few treatment options in the past.
