Placental precursor stem cells require testosterone-free environment to survive
Trophoblast stem cells (TSCs), cells found in the layer of peripheral embryonic stem cells from which the placenta is formed, are thought to exhibit "immune privilege" that aids cell survivability and is potentially beneficial for cell and gene therapies. view more (2009-10-29)
Facial transplants are justified, say experts
With news of the world's first facial transplant hitting the headlines, experts in this week's BMJ debate whether the benefit of this procedure to someone with severe facial deformity outweighs the risk of long term suppression of the immune system. view more (2005-12-09)
Researchers Find Defects in Adult Stem Cell Niche May Cause Breast Cancer
Researchers at Georgetown's Lombardi Comprehensive Cancer Center have found that the onset of breast cancer may be due to defects in somatic adult stem cell niches that exist long before tumors develop. view more (2005-10-05)
Forsyth scientists gain new understanding of adult stem cell regulation
Forsyth Institute scientists have discovered an important mechanism for controlling the behavior of adult stem cells. Research with the flatworm, planaria, found a novel role for the proteins involved in cell-to-cell communication. view more (2007-08-01)
Breast stem cells have features similar to 'basal' tumors
The most aggressive form of breast cancer may originate from breast stem cells that have undergone genetic mishaps. view more (2006-07-20)
Hopkins scientists find cells responsible for bladder cancer's spread
Johns Hopkins scientists have tracked down a powerful set of cells in bladder tumors that seem to be primarily responsible for the cancer's growth and spread using a technique that takes advantage of similarities between tumor and organ growth. view more (2009-08-07)
Researchers link early stem cell mutation to autism
In a breakthrough scientific study published today in the Proceedings of the National Academy of Sciences, scientists at the Burnham Institute for Medical Research have shown that neural stem cell development may be linked to Autism. view more (2008-07-01)
USC researchers discover breast cancer stem cells in bone marrow
Almost all tumor cells found in the bone marrow of early stage breast cancer patients appear to be breast cancer stem cells, suggesting the risk of disease spread for all breast cancer patients may be greater than previously thought. view more (2006-10-09)
Dampened hopes for transplanting bone marrow stem cells in heart attacks
There is little, if any, evidence that adult stem cells can build other cells in an adult organism than those formed in the organs they themselves come from. At any rate, blood stem cells do not convert to heart muscle cells in a damaged heart, which was previously hoped. This has been shown by a research team from the Stem Cell Center at Lund... view more... (2004-05-06)
Tumor suppressor gene in flies may provide insights for human brain tumors
In the fruit fly's developing brain, stem cells called neuroblasts normally divide to create one self-renewing neuroblast and one cell that has a different fate. But neuroblast growth can sometimes spin out of control and become a brain tumor. view more (2009-06-23)
Ovarian cancer stem cells identified, characterized
Researchers at Yale School of Medicine have identified, characterized and cloned ovarian cancer stem cells and have shown that these stem cells may be the source of ovarian cancer's recurrence and its resistance to chemotherapy. view more (2008-04-18)
Regulating Californian stem cell research, and more
Regulations governing human stem cell research must strive to assure strict oversight while simultaneously fostering scientific innovation through collaboration, says a group of scientists from the California Institute for Regenerative Medicine (CIRM), one of the world's largest supporters of such research. view more (2007-05-08)
Study suggests use of stem cell transplantation is beneficial treatment of type 1 diabetes
A therapy that includes stem cell transplantation induced extended insulin independence in patients with type 1 diabetes mellitus. view more (2007-04-11)
Bones hold the key to blood renewal
Though we think of them as solid and permanent, our bones are actually constantly being rebuilt throughout our lives. A team of scientists at the Weizmann Institute of Science has now revealed how cells that work at remodeling the bones play a direct part in the ongoing renewal of another system — the blood. view more (2006-06-20)
To evade chemotherapy, some cancer cells mimic stem cells
Anti-cancer treatments often effectively shrink the size of tumors, but some might have an opposite effect, actually expanding the small population of cancer stem cells believed to drive the disease, according to findings presented today in Atlanta, Georgia at the American Association for Cancer Research's second International Conference on... view more...

Standards in stem cell research
Standards in stem cell research help both scientists and regulators to manage uncertainty and the unknown, according to new research funded by the Economic and Social Research Council. view more (2008-07-21)
Pittsburgh researchers identify source of multipotent stem cells with broad regenerative potential
In a promising finding for the field of regenerative medicine, stem cell researchers at Children's Hospital of Pittsburgh of UPMC have identified a source of adult stem cells found on the walls of blood vessels with the unlimited potential to differentiate into human tissues such as bone, cartilage and muscle. view more (2008-09-22)
Penn researchers find key developmental pathway activates lung stem cells
Researchers from the University of Pennsylvania School of Medicine found that the activation of a molecular pathway important in stem cell and developmental biology leads to an increase in lung stem cells. Harnessing this knowledge could help develop therapies for lung-tissue repair after injury or disease. view more (2008-06-18)
Predicting outcomes for kidney transplant patients
A new study in the American Journal of Transplantation cites evidence in favor of using the protein biomarkers NGAL and IL-18 as a means to determine whether kidney transplant patients will require dialysis within the first week of transplant surgery. view more (2006-04-26)
Adult stem cells are touchy-feely, need environmental clues
A certain type of adult stem cell can turn into bone, muscle, neurons or other types of tissue depending on the "feel" of its physical environment. view more (2006-08-25)
