Nikkei is reporting that the RIKEN internal attempt to replicate so-called STAP (acid bath) cells has failed. Update: apparently, although RIKEN calls the efforts preliminary, the team tried to make STAP an amazing 22 times and 22 times it failed. The rumors for weeks in the stem cell gapevine that RIKEN itself could not get […]

A new patent dispute has exploded in the stem cell field related to induced pluripotent stem (iPS) cells. What’s going on? In 2006, Shinya Yamanaka reported cellular reprogramming to create mouse induced pluripotent stem (iPS) cells in Cell and the next year multiple groups along with Yamanaka’s reported creating human iPS cells. It’s no exaggeration

In some ways it’s hard to imagine that it was only just over 6 months ago that Nature published the two STAP cell papers by a collaborative team of Japanese and American researchers. It feels like years have gone by since then because so much has happened related to the STAP mess including the retraction of the

Today has been a dark day of mourning for science following the death by suicide of Dr. Yoshiki Sasai. I did not know Dr. Sasai personally, but was very impressed with his work. His suicide leaves me feeling very sad and it seems like an appropriate time for reflection. (update I did a post on suicides by

Stem cell-based Regenerative Medicine has huge power for good in the clinic and at the same time great potential for economic development. Those two things go hand in hand. As I argued in my stem cell book, biotech commercialization of stem cells is not a bad thing, but rather if it is done responsibly it

The Obokata STAP cell papers in Nature were retracted today. It feels like it’s been a long time coming in one way as for months now it has felt like retraction was inevitable, but it’s been extraordinarily fast in another way as retractions almost never happen this fast. It’s a day of mixed feelings. This

What is the Vacanti Mouse? Comedian John Oliver has an absolutely blistering segment (see below) on Dr. Oz in which he skewers the physician huckster. The video includes incredibly telling Oz testimony before Congress in which the celebrity doctor seems frankly pretty pathetic and cannot answer even simple questions about his selling of arguably snake oil on

What were people saying about STAP cells at the ISSCR 2014 meeting? It was a tale of two meetings when it came to STAP at ISSCR. Officially, bigwigs at the podiums only briefly mentioned it and they seemed to collectively argue that STAP was something unfortunate, but that the bigger danger was the overreaction to
