The stem cell controversy

''A former member of one of the most prominent stem-cell research teams has been found guilty of falsifying data. New Scientist explains why the group's work is important, looks at where the findings stand now, and asks: what are the implications for the rest of stem cell biology?
...
The University of Minnesota launched a second probe, which has now ruled that this and other images in the Blood paper were "altered in such a way that the manipulation misrepresented experimental data". The investigating panel pinned the blame on Morayma Reyes, then a PhD student at Minnesota, who was the first to isolate MAPCs. She is now at the University of Washington in Seattle.

Where does stem cell research stand now?

It seems clear that MAPCs are not as versatile as ESCs. In any case, biologists can now make a variety of adult cells behave like ESCs, using a genetic "reprogramming" technique pioneered by Shinya Yamanaka of Kyoto University in Japan (read our interview with Yamanaka).
