Fact-checking stem cell stroke therapy: hope but not there yet

Stem cell stroke therapy

Stem cell stroke therapy research has generated buzz over the years. The goal of today’s post is to fact-check claims about supposed stem cell stroke therapies and educate readers on where clinical research stands. There is some real hope here in the long run, but things have been greatly exaggerated at times. Some clinics are

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

He Jiankui says he’s back in the lab after prison for CRISPR babies

He Jiankui

Earlier this year Chinese researcher He Jiankui finished his prison sentence. When I saw that news I wondered about the next chapter for him. It seems he’s already back in the lab doing genetics research. At least that’s according to a blog by He Jiankui himself. Can we trust that what he has written on his website is

Updates on CRISPR therapy development and clinical trials

When I first heard of CRISPR gene editing I was excited for my lab to try it out, but it seemed a long way from the field having even one CRISPR therapy available to treat human disease. In the Knoepfler lab, we study genetic and genomic programming in human development and disease. Gene editing seemed

Stem cells & the philosopher’s stone, P53, thyroid organoids

philosopher's stone

I hadn’t remembered the history of the philosopher’s stone until reading a new review article about stem cells and aging. Here’s the article. Is the philosopher’s stone to rejuvenate blood stem cells an epigenetic regulator? Nature Aging. This preview kind of piece discusses how inhibiting a specific factor called PHF6 can “rejuvenate” HSCs in mice.

CRISPR gene editing

As both a scientist who works on stem cells, cancer, and CRISPR, and a research advocate I’ve been fortunate to meet many patient advocates over the years. Some have been participants in clinical trials themselves. Benefits & risks of clinical trial participation It is very sobering to find out that a clinical trial participant has

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
