Big patent & IP implications or even ‘war’ from STAP stem cells?

A new article in the major Japanese newspaper, Asahi Shimbun, just came out suggest major intellectual property (IP) and patent issues related to stem cells including the new stress induced STAP stem cells. The piece is entitled provocatively enough “Global patent war looms with epoch-making discovery of STAP cells“. That’s strong language. The article begins …

STAP stem cell poll: interesting results & regional differences

I’ve been doing a poll on the extent to which people believe or do not believe in the stress-induced STAP stem cells reported in Nature last week. In just a few days of poll, we’ve got almost 400 respondents, which is great. It’s still not a scientific poll, but the results (above) are interesting for …

Interview with Charles Vacanti on STAP Cells: Link to Spore Stem Cells & More

Obokata-FIg.-2a

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 …

More thoughts from STAP acid reprogramming stem cell paper

The STAP papers on making iPS like cells using acid treatment of differentiated cells really has people talking. See embryo at right made from GFP reporter STAP cells that glow green. As I said in my review of the papers yesterday, there are still some critical things we do not know about STAP cells and I …

Review of Obokata STAP cells Nature papers

STAP-stem-cells

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. No genes. No proteins. No …
