What About Us, Wonder iPS Cells

A post at Science Progress hopes to remind everyone that even though stem cells are currently getting a bit of glory that iPS cells may eventually be a key tool. The post points to an article in last week's Cell in which Rudolf Jaenisch and his colleagues made iPS cells from Parkinson's disease patients' fibroblast cells that lacked viral factors and to another article in Nature from Andras Nagy's group that used transposons instead of viruses to reprogram the cells. It adds, though, that to make sure all the "kinks in the reprogramming process" are worked out, "we need to research human cells going all the way back to the embryonic stem stage."
