Moriguchi

I’m getting some heat from some stem cell folks who think I should not have blogged about the Moriguchi iPS cell transplant case. Their argument seems to be it would have been preferable to either (A) not blog about the story at all or only minimally so fewer people would know about it or (B) …

Texas Guv Perry visits human embryonic stem cell lab at Scripps Institute

February 1, 2021 / By / 7 Comments

Please note that this is one of the only instances in the history of this blog that I have retroactively edited a post for what I believe was an error on my part related to what I feel was overly extreme verbiage. I have also subsequently been informed confidentially of more of the facts of …
