Stem cell breakthrough closes gap between mouse and human studies

摘要

Scientists have shown for the first time that embryonic seem cells are able to self-renew without the natural chemicals that scientists have so far used to maintain them and grow stem cell lines.This discovery contradicts previously held views and could have wide-ranging implications for stem cell research.It is hoped the findings,from the Cambridge team and published in Nature,will lead to a bettet biological understanding of ES cells and more straightforward translation of detailed work done only in mouse ES cells to date.
