What are VSELs and why are more clinics selling them?

One of the more controversial areas in the stem cell field has been over a stem cell type that only a handful of researchers have been able to find and study: very small embryonic-like stem cells or VSELs. These days some are calling them V-cells too. I’ve been getting an increasing number of questions from …

What do you think of all chemical reprogramming? Take our poll

How important is the new development of all chemical reprogramming to make iPS cells? The group led by Hongkui Deng at Peking University in Beijing reported in Science that they used 7 chemicals to make what appear to be mouse iPS cells. I’m hearing a wide range of opinions directly from people in the know. What’s …

Time to bone up on homologous use in the stem cell field

What does homologous use mean? Navigating the arena of clinical use of a biologic such as stem cells or differentiated cells made from stem cells can be challenging. There are many important issues including what defines “minimal manipulation” of biologics such as cells. One particular issue that is critically important and has drawn less attention …

FDA & Japanese Health Ministry (厚生労働省) To Develop iPS cell clinical rules

FDA3-300x2581

In a rare sign of stem cell international regulatory unity, the Japanese Health Ministry (厚生労働省) and the US FDA have agreed to develop a joint, unified regulatory framework for clinical studies of human iPS cells for use in treating retinal diseases. Presumably the rules would also guide clinical use of iPS cells to treat other …

Rip Van Wrinkle: Olay-funded stem cell research on supposed ‘fountain of youth’

I predict that cosmetics firm Olay will announce an anti-aging cosmetic product specifically based on stem cells in some way soon. But can stem cell technology now really make you younger? No, according to the best science; maybe at some point in the future. Yes, according to a hypeful HuffPost piece, which discussed work by a …

Moriguchi 2.0: more papers, more claims, and a new mysterious co-author

Remember Hisashi Moriguchi? He’s the fellow who claimed to have transplanted cells made from induced pluripotent stem (iPS) cells into human patients, to have worked at Harvard, and so forth. It all turned out not to be true. He even admitted it. Now Moriguchi is back in the news. He has several more papers published …
