Stem Cells News and Research

RSS

Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

New finding provides researchers with renewable source for macrophages and neutrophils

A new approach to generating large quantities of two types of white blood cells that are critical for destroying invading bacteria, viruses and other pathogens in humans has been developed by researchers at the University of California, San Diego (UCSD) School of Medicine.

Placental growth factor may help body repair heart attack damage

Heart attack patients produce higher levels of a natural substance in the body that plays a role in the growth of new blood vessels and this over-expression of placental growth factor (PlGF) may help reduce damage to the heart muscle

The Notch effect steers stem cells into cells of the nervous system

Stem cell scientists at the University of Edinburgh have discovered that Notch, a protein first discovered more than 80 years ago in the fruit fly, directs unspecialized embryonic stem cells to become cells of the nervous system.

Dasatinib provides significant benefit in chronic myeloid leukemia patients resistant to Gleevec

A study led by researchers from the Howard Hughes Medical Institute has found that dasatinib provides significant benefit in chronic myeloid leukemia (CML) patients resistant to Gleevec.

Single dose of stem cells produce robust behavioral recovery in animal models for stroke, cerebral palsy

A single dose of adult donor stem cells given to animals that have neurological damage similar to that experienced by adults with a stroke or newborns with cerebral palsy can significantly enhance recovery from these types of injuries, researchers say.

Minimal nutritional requirements for growing and maintaining human embryonic stem cells

Researchers at Yale have established the minimal nutritional requirements for growing and maintaining human embryonic stem cells, a recipe that is critical for clinical application and for developmental studies, according to a report in the Proceedings of the National Academy of Sciences.

Adult stem cells can be used to make new tendon or ligament tissue

Weekend athletes who overexert themselves running or playing basketball may one day reap the benefits of research at the Hebrew University of Jerusalem that shows that adult stem cells can be used to make new tendon or ligament tissue.

Dysregulation of the Hedgehog pathway in human hepatocarcinogenesis

The unchecked activity of a cell signaling pathway crucial in embryonic development and the liver's response to injury leads to liver cancer, researchers from Duke University Medical Center and John Hopkins University School of Medicine have found.

Novel therapy for chronic graft-versus-host disease

A study by Dana-Farber Cancer Institute researchers offers the strongest evidence yet of the effectiveness of a novel therapy for chronic graft-versus-host disease (GVHD), a potentially life-threatening complication of donor bone marrow and stem cell transplants.

Procedure cures some diabetic mice, but not in the way previously reported

Researchers attempting to reproduce a controversial 2003 mouse experiment suggestive of a cure for type 1 diabetes have found evidence that the experimental procedure does eliminate diabetic symptoms in a small fraction of the mice exposed to it.

Study provides a boost for efforts to reverse type-1 diabetes

Researchers have been able to confirm most but not all of the results of a high-profile study that brought new hope to diabetes patients. This study provides a boost for efforts to reverse type-1 diabetes in recently diagnosed patients but not for efforts to grow new islets from spleens.
