patricia derges indictment for fake stem cells sm

A grand jury indicted Missouri state representative and assistant physician Patricia Derges for allegedly selling and injecting patients with fake stem cells. The injection was reportedly just of amniotic fluid, but Derges allegedly claimed it was a stem cell treatment. NBC News was one of several media outlets that broke the story here after the

What are induced pluripotent stem cells or IPS cells?

induced pluripotent stem cells clinical trials map

Induced pluripotent stem cells or iPS cells just might be the most exciting development in the stem cell field over the last 15 years. They have unique potential for clinical impact for regenerative medicine too. This may manifest both through their use to produce differentiated cellular therapies and indirectly via disease modeling as well as

Nociceptor-mediated HSC mobilization. "Schematic representation showing that nociceptive-nerve-derived CGRP, but not substance P, acts via CGRP receptors on HSCs to enhance their mobilization via a cAMP-mediated signalling pathway. "Gao et al Nature, Capsaicin acts via nociceptor signaling to mobilize blood stem cells.

The stem cell paper of the week is a fun one about how capsaicin and nociceptors reportedly mobilize blood stem cells.  However, since the authors only show this in mice, could it also happen in humans? They argue it’s likely happening in people too. Note that nociceptors are special structures in our bodies that sense

What are totipotent stem cells & what can they do?

Multipotent & totipotent vs pluripotent stem cells, very early human embryos totipotent stem cells

Sometimes patients or my students ask me, “What are the best stem cells?” what information are they looking for? I think they often are looking for the most powerful stem cells so perhaps they should be asking, “What are totipotent stem cells?” Other times it seems what patients specifically want to know is what might

It’s fitting, given the edginess over the election, that Halloween is falling only a few days before election day so here is a list of recommended stem cell reads for you to dive into some biomedical science. Liver buds from stem cells Generation of human induced pluripotent stem cell-derived liver buds with chemically defined and

Trump, GOP hypocrisy on Regeneron COVID-19 fetal, stem cell work

293T-HEK-cells-Trump-fetal-stem-cells-sm

Are Trump and the Republican Party showing major hypocrisy over Trump’s use of experimental COVID-19 therapies in part developed by Regeneron using embryonic and fetal cells? The Internet is kind of blowing up over this. Trump’s collision with stem cells For example, people are directly confronting Trump on Twitter over his recent all caps tweet
