Donor T cells change the fate of stem cells in transplantation
When a transplant patient suffers complications such as graft rejection or graft-versus-host disease, physicians attempt to stop the body's immune response by targeting a patient's T cells.   view more (2006-07-13)

Stem cells and cancer: cancer pathways that also control the adult stem cell population
Speaking today (10 April) at the UK National Stem Cell Network Annual Science Meeting in Edinburgh, Professor Alan Clarke from Cardiff University describes his work to investigate a mechanism that normally drives adult stem cells to repair the intestine.   view more (2008-04-10)

Master regulatory gene of epithelial stem cells identified
The skin's ability to replace the tissue it sloughs off is controlled by a variety of genes. A new study from Harvard Medical School published in the May 4 issue of Cell, however, identifies a "master regulator" of this regeneration process not only for skin, but for many epithelial... view more (2007-05-04)

Columbia University Medical Center researchers discover potential mechanism for tumor growth
Researchers at Columbia University Medical Center have identified an inherent feature of stem and progenitor cells that may promote initiation and progression of cancerous tumors.   view more (2005-12-16)

The European Science Foundation publishes policy briefing for human stem cell research
The policy paper recommends the permission of studies of stem cells from embryos and adults, reproductive cloning should not be permitted, but therapeutic cloning should be allowed. There are many chronic, serious and disabling human diseases such as, Parkinson's Disease, Cystic Fibrosis and... view more (2001-06-25)

Faults in newly discovered breast stem cells may lead to tumours
Victorian Breast Cancer Research Consortium scientists from The Walter and Eliza Hall Institute, using a mouse model, have discovered the rare stem cell that drives the formation of all breast tissue.   view more (2006-01-05)

Hopes for new cell therapies 'stem' from Sheffield
The Centre for Stem Cell Biology (CSCB) at the University of Sheffield is welcoming some of the world's leading experts to its International Human Embryonic Stem Cell Symposium on Friday 9 July 2004. The CSCB is a world-leading centre for stem cell research, and has produced two of the UK's six... view more (2004-07-06)

DFG remains skeptical of the cloning of human cells
According to a paper published in the journal Stem Cells, an American group has succeeded in inserting cell nuclei from human skin cells into human enucleated oocytes and to stimulate these new cells to undergo cell division in the laboratory.   view more (2008-01-23)

Progress being made in exploring potential use of stem cells to treat heart disease
Scientists are making headway in exploring the potential future use of stem cells to treat heart disease, according to a review article in the current issue of Nature (June 29, 2006).   view more (2006-06-29)

Treating male infertility with stem cells
New research has examined the usefulness of bone marrow stem cells for treating male infertility, with promising results. The related report by Lue et al, "Fate of bone marrow stem cells transplanted into the testis: potential implication for men with testicular failure," appears in the... view more (2007-03-02)

Stem cells may solve mystery of early pregnancy breast cancer protection
The answer to why an early pregnancy seems to protect against breast cancer could rest with a decrease in stem cells found after animals have given birth, said researchers at Baylor College of Medicine in a report that appears in the current issue of the journal Stem Cell.   view more (2008-09-17)

Want a reason to love your lower belly fat? It's rich in stem cells
Fat removed from the lower abdomen and inner thigh through liposuction was found to be an excellent source of stem cells, with higher stem cell concentrations than other areas of the body.   view more (2008-07-24)

UCLA researchers identify leukemia stem cells
Stem cell researchers at UCLA have identified a type of leukemia stem cell and uncovered the molecular and genetic mechanisms that cause a normal blood stem cells to become cancerous.   view more (2008-05-27)

ESC Congress 2004: Converting cells into heart muscle
Bone marrow derived stem cells can give rise to heart muscle cells. This plasticity concept - the ability of bone marrow cell to transdifferentiate into heart muscle cell - is supported by experimental and clinical data. Another possibility is to replace the missing function by causing... view more (2004-08-30)

Penn study finds hyperbaric oxygen treatments mobilize stem cells
According to a study to be published in the American Journal of Physiology-Heart and Circulation Physiology, a typical course of hyperbaric oxygen treatments increases by eight-fold the number of stem cells circulating in a patient's body.   view more (2005-12-29)

Discovery suggests why stem cells run through stop signs
Everyone knows that stem cells are controversial. Many people know that stem cells can grow into virtually any cell type found in the body, from a red blood cell to a muscle cell to a brain cell. But no one really knows why stem cells continue to divide and renew themselves long after the point... view more (2005-06-13)

Mechanism for regulation of growth and differentiation of adult muscle stem cells is revealed
During muscle regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue.   view more (2007-12-10)

Signaling for cartilage
Skeletal progenitor cells differentiate into cartilage cells when one master gene actually suppresses the action of another, said Baylor College of Medicine researchers in a report that appears online in the journal Proceedings of the National Academy of Sciences.   view more (2006-11-28)

Researchers discover important tool in understanding differentiation in human embryonic stem cells
Researchers at the University of Minnesota's Stem Cell Institute have described how an existing genetic tool can be used to study how human embryonic stem cells differentiate. The research appears in the November 2007 issue of Experimental Biology and Medicine.   view more (2007-10-25)

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)

Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state
For more than 25 years, stem cells have been defined based on what they can become: more of themselves, as well as multiple different specialized cell types.   view more (2007-06-20)

UCLA researchers develop T-cells from human embryonic stem cells
Researchers from the UCLA AIDS Institute and the Institute for Stem Cell Biology and Medicine have demonstrated for the first time that human embryonic stem cells can be genetically manipulated and coaxed to develop into mature T-cells, raising hopes for a gene therapy to combat AIDS.   view more (2006-07-05)

The University of Sheffield has received a £2.6m grant to create some of the world's first embryonic stem cell lines that can be used for medicinal purposes.   view more (2005-03-16)

Neural stem cells derived from human embryonic stem cells carry abnormal gene expression
Neural stem cells grown from one of the federally approved human embryonic stem cell lines proved to be inferior to neural stem cells derived from fetal tissue donated for research, a UCLA study has found.   view more (2006-08-07)
