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 papers and the tragic death of one of the STAP authors, Dr. Yoshiki Sasai, last week. Where does the STAP story go from here? Is it over? In a …Read More

The recent publication of two Nature papers by a team in part led by Dr. Charles Vacanti on acid treatment produced stem cells (so-called STAP stem cells) has been a blockbuster story in the stem cell field and has grabbed major global media attention as well. For background my review of the paper here and more thoughts here. Many people understandably want to learn more about STAP stem cells.  For that reason, I invited Charles Vacanti to do an interview on my blog. Dr. Vacanti is Professor of Anaesthesia and head of …Read More

I’m getting some heat from some stem cell folks who think I should not have blogged about the Moriguchi iPS cell transplant case.

I don’t really buy either argument. Let’s go over the timeline. On October 10th, Hisashi Moriguchi reportedly presented his …Read More

Hisashi Moriguchi had a poster up at the NY Stem Cell Meeting yesterday and has done interviews with Japanese media saying that he has led a team that transplanted iPS cells into human patients. Reportedly his poster said and the newspaper articles have stated that the iPS cell transplant work had IRB approval from Harvard Medical Medical School/MGH. Two papers of his published this year also state that the work done in those publications also had Harvard Med School IRB approval. I directly asked …Read More

It’s a confusing time at the Vatican, which arguably has an international stem cell scandal of its own making on its hands. What the heck is going on? In an embarrassing move, they organized a stem cell conference for this year and then abruptly cancelled it, with the reason being that they had originally invited a number of prominent embryonic stem cell supporters/researchers to be speakers. There appears to be a huge schism in the Church over stem cells as one faction organized this …Read More
