The stem cell field has puzzled on and off for years over a constellation of papers on purported stem cells including so-called VSEL and MUSE cells. Many of us haven’t been convinced that these are real stem cells. I see VSEL and MUSE fitting into a larger pattern of dubious stem cell claims including the STAP […]

There have been many other interesting scientific and specifically regenerative medicine developments and papers this past week including with CIRM and exciting CIRM funding to UC Davis so read on, but first a somewhat random question: are you more of a cat person or dog person? I’d say I’m both. But our big dog is

Retraction Watch broke the news that Haruko Obokata of the STAP cell train wreck now has a 4th paper retraction. The publication related to the controversial idea that adult tissues have pluripotent potential or actual pluripotent stem cells in them so it was kind of foundational for the debunked STAP cell idea. It also reminds

The stem cell universe is populated by sometimes mysterious acronyms (see an image of a whole alphabet stem cell acronym soup), many of which refer to specific kinds of stem cells including one nebulous type called MUSE cells. MUSE cells clinical trials I’m not convinced that MUSE cells exist, but oddly there appear to be
MUSE cells are in 4 Japanese stem cell trials despite doubts Read More »
Once upon a time this blog and major outlets around the world were regularly writing about a Japanese stem cell researcher named Haruko Obokata (小保方 晴子). Whatever happened to Obokata and the other folks directly involved in STAP cell research? First, a bit of background because maybe still a few people never heard of STAP cells

When I was a kid there was this commercial on TV for Chiffon margarine (fake butter) with the slogan, “It’s not nice to fool mother nature!” As a kid I thought it was dumb but kind of funny. A modified version of that mother nature advertising slogan has become a cultural tagline. Don’t mess with

Something very strange just happened at the journal Nature related to what’s called Muse cells. Kudos to them for dealing with it quickly though. They published an unreviewed research “article” on controversial (perhaps non-existent) stem cells called “Muse cells” that was actually a paid advertisement. After I communicated with the Nature team eventually they ended up

STAP is back? Really? No, I don’t believe so, but there’s an interesting development and twist on the STAP cell front. Just a few days ago on January 4, 2017 Dr. Charles Vacanti, the originator of the STAP cells concept, submitted a declaration to the USPTO affirming the belief that STAP cells are real and requesting that

Each year around this time I check up on my past year’s predictions for the stem cell field. For 2015 I made 20 predictions. You can see past 10 predictions lists for 2013 and 2014. It’s pretty interesting to look back at where the focus was in past years and what my crystal ball yielded
How did my 20 stem cell predictions for 2015 fare? Read More »
Each year towards the end of December I make predictions for the coming year as I did for 2015. In the past I usually make a top 10 prediction list, but for this year I made 20 predictions. Admittedly some of them may have been more hopes than predictions. At mid-year today on June 30th,
