Today was day one of the Houston Stem Cell Summit, at which Guv Rick Perry was a keynote speaker. I thank the organizer for inviting me to attend and I wish I could have, but I’ve spent a good chunk of the day today teaching medical students right here in Sacramento, CA so I could […]

I was fortunate enough to do my postdoctoral studies at the Fred Hutchinson Cancer Research Center (aka “The Hutch”) in Seattle. I was a postdoc for more years than I’d like to admit, but it was a wonderful experience. The Hutch is the kind of place where you can imagine making the impossible become possible

The Houston Chronicle has posted the response letter from Celltex to the FDA in regard to the FDA Warning Letter issued to Celltex. The Chronicle also has a piece up on the warning letter that is a great read here. My thoughts on the possible paths for Celltex moving forward can be found here. The

Hisashi Moriguchi. He is arguably at the center of one of the biggest science scandals of 2012. This is the guy who lied about doing iPS cell transplants into human patients. He also lied about being affiliated with Harvard & its primary teaching hospital, Massachusetts General Hospital (MGH), for many years after he left there. He

A team from the Salk Institute in La Jolla led by Inder Verma has reported dedifferentiation in a paper in Science some important findings that I believe make their paper in the top 10 as a candidate for paper of the year. The paper, entitled “Dedifferentiation of Neurons and Astrocytes by Oncogenes Can Induce Gliomas

The FDA warning letter that Celltex received in late September (but that just went public yesterday–see my initial reaction here) is a possible game-changer for that company in my opinion. Why? The letter outlined in great detail the FDA’s concerns with how Celltex manufactures its stem cell product ranging from lack of documentation to concerns about aseptic/sterile

Sugarland, Texas stem cell clinic, Celltex, is most well known for having done the stem cell treatment on Texas Governor Rick Perry. What’s up with Celltex this week? There has a lot of talk behind the scenes that something big has happened. Very recently Celltex put out a PR recently saying it had received a
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)

The fellow at the center of what appears to be a made up story about iPS cell transplantation into humans is named Hisashi Moriguchi. Two new articles in the Japanese media support the notion that he has made the whole iPS cell transplant story up: here and here. Most people I’ve talked to in the

My phone has been ringing and my email flowing at an even faster rate than usual over this still breaking story of the reported transplant of iPS cells into human patients by a Japanese scientist, Hisashi Moriguchi , who at some point was a visiting scientist at Harvard, apparently no more recently than 12 years ago.
