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 not a fan of cats so I have to get my random cat time in on walks if I happen to run into a cat. I crossed paths with …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 and Obokata or forgot the key points behind the controversy. Haruko Obokata became well known because of her research claiming to make pluripotent stem cells like IPS cells without …Read More

Some unproven stem cell clinics just make things up, but when a big medical organization like Seattle’s largest nonprofit health firm, Swedish Medical Group, has a marketing segment on TV with what in my view are odd and inaccurate claims related to regenerative medicine, the negative impact could be far greater. The segment in question was a sponsored content piece on KING 5 TV, essentially a medical ad for unproven stem cells and regenerative medicine. In my original post I list what I see …Read More

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 pulling down the ad/article as of today. How can a research article be an advertisement? I don’t think it should be possible. An “ad/article”? Of course, research journals run …Read More

Are MUSE cells for real? Stem cells come in different types that vary in a key property called “potency”, but very few are pluripotent. The more potency, the greater the flexibility of a stem cell to make other cell types. Flexibility in the cellular world is power. The most powerful stem cells generally used are called “pluripotent”, which refers to a special kind of stem cell that can make all 200+ other types of cells in the body through differentiation. Pluripotent stem cells are hard …Read More
