It’s been an important week for stem cells. Although I’ve been busy working on multiple grants and papers, when I take a break I like to read up on what’s been going on with stem cells. What are the top stem cell stories and headlines of the week? CIRM awarded Asterias (a subsidiary of BioTime) […]

They say a little knowledge is a dangerous thing and more specifically I say that a little stem cell training for MDs, such as from A4M, can potentially be a dangerous problem too. I’ve been very concerned about self-proclaimed “stem cell training courses” for MDs. These kinds of courses have claimed that over as short as a

Very small embryonic-like stem cells aka VSELs are reported to be tiny adult stem cells that are pluripotent or non-existent depending on whom you talk to most recently or which paper you just read. These very controversial cells (which I once compared to the Sasquatch) have a wildly fluctuating history with their existence on multiple occasions

A small group of the STAP authors via RIKEN have now released a detailed protocol also available at Nature Protocol Exchange for making STAP stem cells entitled “Essential technical tips for STAP cell conversion culture from somatic cells”. This comes about 5 weeks after publication of their Nature STAP stem cell papers. 2020 update: With the 4th and

I don’t know about you, but this whole STAP stem cell thing has got me kind of bummed out. Last night I was thinking to perhaps stop blogging about it as the situation turns darker, but it seems like it wouldn’t do any good to ignore it. The ostrich with head in the sand approach

If you take an ordinary cucumber and soak it in a mild acid solution of vinegar for a few weeks you get a pickle, which is where we find STAP stem cells. Recently, some scientists reported in Nature that if you take ordinary cells and soak them in a mild acid solution for 30 minutes,

In two Nature papers (here and here) published today researchers report the astounding finding of reprogramming differentiated cells back to a pluripotent or even totipotent state simply by exposing the cells to extreme environmental stress, creating cells they called STAP cells. Update: see more thoughts on STAP stem cells here. STAP cells: stressing the cell

Tonight, President Obama will give his “State of the Union” annual address on how our country is doing. I’m guessing he will say the state of the union is positive, but with challenges. What is the state of the union for stem cells in America today? Overall I think it’s extremely encouraging and the field

The Oregon State Medical Board took emergency action to suspend the medical license of Dr. Kenneth Welker of Eugene, Oregon on Thursday. Update: Unfortunately, the Associate Press (AP) story on this topic (discussed more below) contains numerous important mistakes including thoroughly mixing up embryonic, adult, and induced pluripotent stem cells (iPSC). Keep that in mind. Also, sadly
