Where do things stand with IPS cell translational research? The newest development is that regulators in Japan just have given conditional approval to an Osaka University team to an induced pluripotent stem (IPS) cell-based study for ischemic heart disease. For years IPS cell-based products have been on-again off-again in active clinical study for macular degeneration, work led by Dr. Masayo Takahashi. The new heart disease study is led by Yoshiki Sawa. This appears to be the third conditionally approved IPS cell study in Japan. I’m not …Read More

I’ve got some TGIF recommend reads on stem cells, etc, but first, what a week, right? We need more action on preventing gun violence. It’s a uniquely American health crisis that doesn’t have to be. There’s no real, common sense reason that gun control can’t reduce mass killings of our kids and others like the latest one in the Florida high school. That kind of gun control won’t interfere with hunting or other legitimate gun ownership. There are clearly going to be politicians who …Read More

A researcher working at Kyoto University has reportedly engaged in misconduct leading to an institutional request for retraction of a paper from the journal Stem Cell Reports. The paper in question appears to have rather large-scale problems: “Kohei Yamamizu, a specially appointed assistant professor at the university’s Center for iPS Cell Research and Application, falsified all six main figures in the paper that claimed he had succeeded in generating a brain structure in vitro using iPS cells, according to Kyoto University.” The Center for iPS Cell …Read More

CRISPR and IPS cells are two of my favorite things so when they come together as in a cool, new paper from Sheng Ding’s lab, I’m excited to read it and curious as to what the scoop is. Since 2006-2007 when mouse and human reprogramming were first reported, many different methods have been explored to make induced pluripotent stem (IPS) cells. Along the way we’ve all learned quite a lot about how pluripotency is regulated, whether it is in the context of maintenance or …Read More
