Powerful technique for multiplying adult stem cells may aid therapies
Adult stem cells may be free of the ethical concerns that hamper embryonic stem cell research, but they still pose formidable scientific challenges. Chief among these is the doggedness with which adult stem cells differentiate into mature tissue the moment they're isolated from the body. view more (2006-01-23)
Brain tumor researchers find their 'niche'
Brain tumors appear to arise from cancer stem cells (CSCs) that live within microscopic protective "niches" formed by blood vessels in the brain; and disrupting these niches is a promising strategy for eliminating the tumors and preventing them from re-growing. view more (2007-01-17)
UCI researchers discover key factor for survival of human embryonic stem cells
Human embryonic stem cells (hES) offer great hope for the treatment of some devastating diseases, but finding a way to keep enough of these cells usable and healthy for transplantation in patients has been an ongoing problem. view more (2006-02-17)
A step forward in stem cell research
According to research published today, investigators from Memorial Sloan-Kettering Cancer Center (MSKCC) have used new techniques in the laboratory that allowed them for the first time to derive unlimited numbers of purified mesenchymal precursor cells from human embryonic stem cells (HESCs). view more (2005-06-27)
UNC scientists turn human skin cells into insulin-producing cells
Researchers at the University of North Carolina at Chapel Hill School of Medicine have transformed cells from human skin into cells that produce insulin, the hormone used to treat diabetes. view more (2008-09-18)
Life and death in the hippocampus: what young neurons need to survive
Whether newborn nerve cells in adult brains live or die depends on whether they can muscle their way into networks occupied by mature neurons. view more (2006-08-14)
Liver Cancer Linked to Cellular Repair Pathway
The unchecked activity of a cell signaling pathway crucial in embryonic development and the liver's response to injury leads to liver cancer. view more (2006-03-30)
New source of multipotent adult stem cells discovered in human hair follicles
Researchers at the University of Pennsylvania School of Medicine have isolated a new source of adult stem cells that appear to have the potential to differentiate into several cell types. view more (2006-07-13)
Cancer cells lose drug resistance following electrical stimulation in vitro
Drug-resistant tumour cells lose their drug resistance when exposed to low intensity, low frequency electric pulses for three days. view more (2006-03-17)
Neural Stem Cells Are Long-Lived
New studies in mice have shown that immature stem cells that proliferate to form brain tissues can function for at least a year - most of the life span of a mouse - and give rise to multiple types of neural cells, not just neurons. view more (2005-10-06)
Harvard scientists identify compounds that stimulate stem cell growth in the brain
cientists at Harvard University have identified key compounds that stimulate stem cell growth in the brain, which may one day lead to restored function for people affected by Parkinson's disease, strokes, multiple sclerosis, and a wide range of neurological disorders. view more (2006-09-01)
Run amok enzyme causes same problems in both humans and fruit flies
An enzyme found at elevated levels in several human cancers has been linked to abnormal tumor growth in fruit flies, a discovery that provides a new model for understanding the link between stem cell biology and cancer, according to researchers at the University of Oregon. view more (2006-12-19)
Testes to incubate stem cells
Men may cringe at the idea, but sperm-producing stem cells found in testicles could be extracted, grown in the lab, and frozen for future use. view more (2006-04-25)
Clues to breast cancer hidden inside stem cells
Stem cells and how to boost them is hot on the research agenda. But stopping them could be critical too, as evidence implicating stem cells in cancer is mounting. view more (2006-04-25)
Iron particles and MRI could replace biopsies to track stem cell therapy and deploy stents
In a series of experiments in animals, researchers at Johns Hopkins have successfully used a technique that tracks mesenchymal stem cells via magnetic resonance imaging (MRI) to monitor the progress of the cells in repairing tissue scarred by heart attack. view more (2005-12-05)
A new link between stem cells and tumors
Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg and the Institute of Biomedical Research of the Parc Científic de Barcelona (IRB-PCB) have now added key evidence to claims that some types of cancer originate with defects in stem cells. view more (2005-09-06)
Markers of brain cell development may help success of stem cell transplants
Four sugar-coated faces made by stem cells as they differentiate into brain cells during development have been identified by scientists. view more (2005-09-07)
Monitoring the response to vaccination against melanoma
A new study published in PLoS Medicine this week describes a way to measure the immune response in people treated with an experimental vaccine to melanoma. view more (2005-09-20)
USC researchers track down the stem cells that create feathers
The stem cells that produce bird feathers have been visualized and analyzed for the first time, signifying the initial step in a scientific journey that may ultimately shed light on human organ regeneration. view more (2005-12-15)
Molecular 'marker' on stem cells aids research, perhaps therapies
A sugar molecule present on embryonic stem cells also has been found on the surface of a type of adult stem cell, a discovery that may help researchers isolate and purify adult stem cells for use in therapies aimed at bone healing, tendon repair and cartilage regeneration, researchers at UT Southwestern Medical Center report. view more (2006-12-04)
