Scientists in stem cell breakthrough

0 comments

New research has led to a breakthough in developing stem cells from regular skin cells, in a move that could save cloned embryos from being destroyed to harvest their stem cells. 

Earlier in the year, scientists succeeded in programming mouse skin cells back to resemble embyonic stem cells and now a team in Japan claims to have done the same thing with human skin cells.
Previously, it was thought the only way to get human stem cells was from four- to five-day old embryos.
The news that this could now be possible without using embryos has been hailed as a major stride in ethical research.
