I would like to express my deepest condolences to Dr. Sasai’s family and colleagues.”
Sasai was a coauthor on two papers published in Nature that purported to offer a quick and simple way of making highly versatile stem cells. Instead of destroying embryos or tinkering with their DNA, the scientists said they produced their flexible cells by stressing them out in an acid bath for 30 minutes and then spinning them in a centrifuge for 5 minutes.
