AP, LA Times, Wash Post, WSJournal, etc: From skin cells to stem cells to fully formed baby mice. Who needs embryonic stem cells now?
In Nature and in Cell Publishing’s journal Stem Cell comes attention-grabbing news this week that teams in China have not only made what look like pluripotent stem cells from mature skin cells – which has been done before - but went and turned some of them into embryos, put them in mouse uteruses, and came up with complete mice. If so, that’s pretty good proof of their pluripotency. The Wall Street Journal‘s Gautam Naik is not alone in pointing out the up and down side of this news. It means less reliance on “controversial laboratory techniques” by which he, farther down, explains as the need for embryos to supply the stem cells. On the other hand, if it proves fairly reliable this could “make it easier to create human clones and babies with specific genetic traits.
The image, from Nature, shows Xiao Xiao (“shau shau”), which means tiny, and is the first baby mouse created from reprogrammed skin cells.
