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... view more (2006-06-20)
'Gateway' gene discovered for brain cancer
Researchers have discovered that the same genetic regulator that triggers growth of stem cells during brain development also plays a central role in the development of the lethal brain cancer malignant glioma. view more (2007-02-15)
Key gene controlling kidney development found
A gene called Six2 plays a critical role in the development of the kidney by keeping a population of "parent" stem cells constantly available to produce the differentiated cells that give rise to specialized parts of the organ. view more (2006-10-11)
Coming soon: Cell therapies for diabetes, cancer?
Therapies using stem cell transplants are advancing promising treatments for such conditions as Alzheimer's Disease, neurological diseases and spinal cord injury, and heart disease. view more (2008-03-20)
Gladstone scientists identify role of tiny RNAs in controlling stem cell fate
Researchers at the Gladstone Institute of Cardiovascular Disease (GICD) and the University of California, San Francisco have identified for the first time how tiny genetic factors called microRNAs may influence the differentiation of pluripotent embryonic stem (ES) cells into cardiac muscle. view more (2008-03-06)
Stem cells transplanted to female foetus
A Swedish case where a certain type of stem cells has been transplanted to a foetus with a serious disease, was made public today. The results suggest that fetal mesenchymal stem cells may be a valuable source for transplantation and cell therapies. view more (2004-12-17)
Discredited Korean embryonic stem cells' true origins revealed
A report from researchers at Children's Hospital Boston and the Harvard Stem Cell Institute sheds new light on a now-discredited Korean embryonic stem cell line, setting the historical record straight and also establishing a much-needed set of standards for characterizing human embryonic stem cells. view more (2007-08-03)
Researchers offer proof-of-concept for Altered Nuclear Transfer
The theory, called altered nuclear transfer (ANT), proposes that researchers first create genetically altered embryos that are unable to implant in a uterus, and then extract stem cells from these embryos. view more (2005-10-17)
Scientists uncover the potential to control adult stem cells
Research being presented today (10 April) at the UK National Stem Cell Network Annual Science Meeting in Edinburgh represents a step towards the use of Adult Stem Cells (ASCs) to repair damaged tissue. view more (2008-04-10)
Bio-engineering of blood vessels
Blood vessel prostheses work best when the biochemical and mechanical properties match reality as much as possible and when they are made of biodegradable material. To this end tissue technologists grow natural vascular wall cells, endothelial cells, in a biodegradable tube made of collagen.... view more (2002-04-16)
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)
Building stronger bones, 1 stem cell at a time
Mesenchymal stem cells (MSCs) are bone marrow-derived cells that are capable of giving rise to various cell types through a process known as differentiation. view more (2008-01-25)
Medium is the message for stem cells in search of identities
Embryonic stem cells, prized for their astonishing ability to apparently transform into any kind of cell in the body, acquire their identities in part by interacting with their surroundings—even when they are outside of the body in a laboratory dish, University of Florida scientists report. view more (2006-07-06)
Putting stem cell research on the fast track
Engineers at Rensselaer Polytechnic Institute have developed tools to help solve two of the main problems slowing the progress of stem cell research - how to quickly test stem cell response to different drugs or genes, and how to create a large supply of healthy, viable stem cells to study from... view more (2007-09-13)
Administering stem cells to patients with myocardial infarction leads to a reduction of the infarct
This week, doctors at the Catholic University of Leuven, connected with the University Hospital-Gasthuisberg, the Stem Cell Institute Leuven (SCIL), and the Flanders Interuniversity Institute for Biotechnology (VIB), are publishing a major breakthrough in the treatment of patients with acute... view more (2006-01-10)
Protein maintains cross talk between cells that control hair growth
Genes, it turns out, are only as active as the signals that turn them on and off. Now scientists from Rockefeller University and the Howard Hughes Institute have identified the signaling molecule that ratchets up and clamps down the activity of key genes in dermal papilla, a type of skin cell whose... view more (2008-02-15)
Protein protects embryonic stem cells' versatility and self-renewal
A protein known as REST blocks the expression of a microRNA that prevents embryonic stem cells from reproducing themselves and causes them to differentiate into specific cell types, scientists at The University of Texas M. D. Anderson Cancer Center report in the journal Nature. view more (2008-03-24)
Reversing cancer cells to normal cells
In earlier work, Northwestern University scientist Mary J.C. Hendrix and colleagues discovered that aggressive melanoma cells (but not normal skin cells nor less aggressive melanoma cells) contain specific proteins similar to those found in embryonic stem cells. view more (2007-04-30)
Row over study puts Korea's scientific community under scrutiny again
This week's BMJ investigates a bitter row over a scientific paper that is putting Korea's scientific community under scrutiny once again. view more (2007-04-09)
Don't ban embryo-based research says new chairman of European fertility organisation
The incoming chairman of an organisation representing over 4,000 international fertility experts has urged the EU not to go down the road of attempting to ban research on embryonic stem cells. Professor Arne Sunde, who takes over tomorrow as chairman of the European Society of Human Reproduction... view more (2003-06-27)
Brittlestar provides new model for stem cell research
The brittlestar, Amphiura filiformis, is a close relative of the starfish and can regenerate lost arms in a matter of weeks. view more (2006-04-10)
Advances In Curing Corneal Illnesses Using Stem Cells
The University School of Clinical Medicine has developed a new technique for the treatment of corneal illnesses. It involves transplanting from the cornea stem cells which have previously been grown in the laboratory. According to the explanation provided by Doctor Javier Moreno, director of... view more (2004-02-16)
Human stem cells delay start of Lou Gehrig's disease in rats
Researchers at Johns Hopkins have shown that transplanting human stem cells into spinal cords of rats bred to duplicate Lou Gehrig's disease delays the start of nerve cell damage typical of the disease and slightly prolongs life. view more (2006-10-16)
Embryonic stem cells accrue genetic changes
An international team of researchers has discovered that human embryonic stem cell lines accumulate changes in their genetic material over time. view more (2005-09-06)
Expression of 'Blimp1' gene leads to the discovery of cells responsible for skin's sebaceous gland
Mice may not get zits, but they do have oily skin. This week, new research on mice from Rockefeller University shows how the cells responsible for oil production develop, and uncovers clues about how stem cells renew and differentiate. view more (2006-08-11)
