There are now three competing approaches to regenerative medicine: embryonic stem cells, induced pluripotent cells, and transdifferentiated cells. In my latest feature article, out in last week's issue of Current Biology, I explored these three options and discussed the implications for medicine and society.
Since writing this piece, one notable side effect occurred to me that I hadn't thought of: the approach of "therapeutic cloning," much debated in around 2004-05, has completely disappeared from the agenda, now that there are options that are both easier and less problematic at the bioethics front.
