Stem cell trigger identified
Last updated: Monday, October 31, 2005
US scientists announced Saturday they had moved a big step closer to growing human organ tissue in the laboratory using embryonic stem cells, according to a report in The Times of London. The discovery could help pave the way for lifesaving treatments for a variety of illnesses, with stem cells someday being used to repair or replace lost tissue.

Reporting in the journal Nature Biotechnology, researchers at biotech company CyThera said they have found a way to turn embryonic stem cells into endoderm, a layer of cells in human embryos that eventually develops into organs.

CyThera scientific director Emmanuel Baetge told the Times that "If you were to use human embryonic stem cells to make products that treat disease such as diabetes or liver failure, you would have to go through the endoderm stage to get (them)."

Experts have hailed the results as proof of principle that stem cells can be manipulated to give rise to endoderm, which has so far been extremely difficult to obtain. – (HealthDayNews)
