Reviews of P shot & O shot stabs at sexual enhancement

Something called a P shot has sparked interest from some men interested in high-risk attempts at enhancement. The goal of today’s review post is to fact-check P shots. They’re sold for supposed penis enhancement or to address erectile dysfunction (ED). I’ll also fact-check so-called O shot stabs at vaginal rejuvenation or enhancement. These are both […]

Marc Tessier-Lavigne

We’ll start with a story related to possible research misconduct, Stanford’s President Marc Tessier-Lavigne, and Science Magazine.  In some ways the news on Science itself could be the bigger long-term story. Marc Tessier-Lavigne pub investigation, Science oops moment Here’s some of the coverage: Stanford investigates potential misconduct in president’s research, Science.

Nurown BrainStorm

I get a lot of questions about stem cells for ALS and more recently people have been specifically interested in NurOwn from BrainStorm Cell Therapeutics. Recently, the FDA denied BrainStorm’s request for a BLA for NurOwn. The company felt its Phase III trial was encouraging. It sounds like they will move forward with a follow-up

What is Mastodon & why so far it’s a clunky alternative to Twitter

Mastodon

Lately it seems like something called Mastodon is on the minds of many a Twitter user. There is a wave of people tweeting “let’s dump Twitter and go to Mastodon now that Musk has taken over!” However, so far I don’t see Mastodon as a solid alternative to the admittedly annoyingly musky Twitter. I do

KRAS mutations, KRAS G12C

If you’ve never heard of the KRAS G12C mutation, it’s a particularly frightening mutation present in numerous cancers. Like the MYC oncogene, many people view mutations in RAS as undruggable, but new efforts show some glimmers of hope. The drug Sotorasib has been approved by the FDA to target the KRAS G12C mutation. Here’s a

Venus, cat chimera

When you are a stem cell biologist and especially if you do a blog, you sometimes run across very strange things like a chimera cat. In this case, I stumbled on the whole topic of chimeric cats because I was searching for info on chimeric rats on Google. Of course, I was. It’s kind of

FDA leader Stephen Hahn was pressured to aid Texas firm Direct Biologics

Former FDA Commissioner Stephen Hahn.

An FDA FOIA dump of text messages of former Commissioner Stephen Hahn suggests that a Texas regenerative firm called Direct Biologics benefited from political pressure on him in mid-2020. Then he was asked again to help in early 2021. This was shortly before he resigned at the start of the Biden Administration. The push came from

Paper sparks renewed interest in transdifferentiation & clinical potential

transdifferentiation, iOPCS

There was a time when I thought transdifferentiation based approaches might quickly move into clinical trials. Then things kind of cooled off. We didn’t see many papers reporting methods to transdifferentiate cells. I still think that this technology, sometimes called direct reprogramming, has major potential. A new paper on making human brain cells this way got
