Your own stem cells can help treat heart disease

Posted on by

Transplanting own stem cells into heart of severe angina patients lessens their pain and improves their ability to walk, a new study has revealed.

The largest national stem cell study for heart disease showed that transplant subjects also experienced fewer deaths than those who didn’t receive stem cells.

In the 12-month Phase II, double-blind trial, subjects’ own purified stem cells, called CD34+ cells, were injected into their hearts in an effort to spur the growth of small blood vessels that make up the microcirculation of the heart muscle (…)

He also said that this study provides the first evidence that a person’s own stem cells can be used as a treatment for their heart disease. However, he cautioned that the findings of the 25-site trial with 167 subjects, require verification in a larger, Phase III study.

The stem cell transplant is the first therapy to produce an improvement in severe angina subjects’ ability to walk on a treadmill. Twelve months after the procedure, the transplant subjects were able to double their improvement on a treadmill compared to the placebo group (…)

Stem Cells Show Promise in Repairing a Child’s Heart

Those suffering from a damaged heart can be treated with their own heart cells. According to a recent research, heart stem cells from children with congenital heart disease can rebuild the damaged heart in the laboratory. The findings apparently have great significance in the health zone.

While conducting the research, cells were achieved from patients ranging in age from a few days after birth to 13 years. These patients were previously subjected to routine congenital cardiac surgery. The number of heart stem cells appears greatest in neonates, that reduce with progression in age. Majority of the stem cells can be possibly found in the upper right chamber of the heart, or the right atrium. The cardiac stem cells seem to be functional and are capable to repair the damaged heart.

“Due to the advances in surgical and medical therapies, many children born with cardiomyopathy or other congenital heart defects are living longer but may eventually succumb to heart failure. This project has generated important pre-clinical laboratory data showing that we may be able to use the patient’s own heart stem cells to rebuild their hearts, allowing these children to potentially live longer and have more productive lives,” shared Sunjay Kaushal, MD, PhD, surgeon in the Division of Cardiovascular Thoracic Surgery at Children’s Memorial Hospital and assistant professor of surgery at Northwestern University Feinberg School of Medicine, lead author of the research.

Study: Stem Cells Fight Multiple Sclerosis

Posted on by

The symptoms of multiple sclerosis could be reversed thanks to stem cell transplants from the patient’s own bone marrow, according to a study that will be published in March in Lancet Neurology by researchers from Northwestern University Feinberg School of Medicine in Chicago, who say that stem cell transplants could restore the immune system of patients suffering from the disease, stopping its evolution, and even causing its regression.

Multiple sclerosis is an autoimmune disease characterized by a defective immune system, which attacks the body’s own tissues in the central nervous system, and effects 57 thousand Italians. The disease develops through a process called “demyelinization”, which causes the deterioration of myelin – sheaths composed of fatty acids that cover nerve fibers – slowing or completely stopping the transmission of nerve impulses along the fibers in the brain and the spinal cord.

Stem Cells Buy Freedom From Insulin for Type 1 Diabetics

A particular type of stem cell transplantation using the patient’s own cells led to short-term freedom from insulin injections in 20 of 23 patients newly diagnosed with type 1 diabetes participating in an experimental protocol in Brazil.

One patient even managed to go four years without needing outside sources of insulin, although the average was 31 months, said the authors of a report in the April 15 issue of the Journal of the American Medical Association, a themed issue on diabetes.

The patients also kept their blood sugar under control, which is key to preventing complications from diabetes. And, the authors stated, increased C-peptide levels indicated that the pancreas’ beta cells were alive and well.

“We were trying to preserve islet beta cell mass, that is, the cells that produce insulin, by stopping the immune system attack on these cells,” said senior study author Dr. Richard Burt, of Northwestern University Feinberg School of Medicine in Chicago. “Why new onset? Because we wanted to make sure there were still some islets there. We don’t believe stem cells form islet cells, but if the islet cells are still there, there might be regeneration if we stop the attack soon enough.”

New study into bladder regeneration heralds organ replacement treatment

A medical model developed for regenerating bladders by using stem cells

Researchers in the United States have developed a medical model for regenerating bladders using stem cells harvested from a patient’s own bone marrow. The research, published in STEM CELLS, is especially relevant for paediatric patients suffering from abnormally developed bladders, but also represents another step towards new organ replacement therapies.

The research, led by Dr Arun Sharma and Earl Cheng from the Feinberg School of Medicine at Northwestern University and Children’s Memorial Research Center, focused on bone marrow mesenchymal stem cells (MSCs) taken from the patient. Previously studies into the regenerative capacity of cells in bladders have focused on animal models, but these have translated poorly in clinical settings.

“Advances in the use of bone marrow stem cells taken from the patient opens up new opportunities for exploring organ replacement therapies, especially for bladder regeneration”, said senior author Sharma. “Several findings from our study have demonstrated the plasticity of stem cells derived from bone marrow which make them ideal for this type of work.”

The team discovered that bone marrow mesenchymal stem cells (MSCs) have phenotypic and physiological similarities with bladder smooth muscle cells (bSMCs) implying that MSCs can serve as an alternative cell source for potentially damaged bSMCs.
