Spicy stem cell pathways & other recommended reads

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 […]

KING 5 TV pulls odd Swedish Medical regen med infomercial off YouTube

Swedish-Adam-Pourcho-Regenerative-Medicine

Some unproven stem cell clinics just make things up, but when a big medical organization like Seattle’s largest nonprofit health firm, Swedish Medical Group, has a marketing segment on TV with what in my view are odd and inaccurate claims related to regenerative medicine, the negative impact could be far greater. The segment in question

Hvad er stamceller?

Hvad er stamceller? Menneskekroppen indeholder hundredevis af forskellige celletyper, der er vigtige for vores daglige helbred.

What is the Billionaire’s blood & stem cell club and how does one get into that? The focus of what I’m satirically calling this “billionaire’s club” is on anti-aging and prolonging life. If you have a lot of money and are willing to take risks on yourself toward some specific goal such as staying young

Divots fly from CNN puff piece on Jack Nicklaus & unproven stem cells

CNN-puff-piece-stem-cells-screenshot-from-video

This past week’s coverage of unproven stem cells exhibited a wide range both in tone and in topics including golfer Jack Nicklaus. There were the three critical articles on clinics that I blogged about earlier and then there was a CNN puff piece by Dr. Sanjay Gupta and Roni Selig mostly focused on Nicklaus. Note that

Iffy stem cell shot in big toe, not what NFL star was hoping

stem-cell-shot-big-toe

Getting a stem cell shot or injection is completely 100% safe, right? An NFL star recently found out just how wrong that stem cell clinic mantra turned out to be. Jordan Reed, tight end for the Washington Redskins, has had issues with his big toe. He apparently thought that a stem cell injection there would

stem-cell-predictions

Below are the 2016 stem cell predictions I made last year and their status now color-coded near year’s end. Green is right, orange is mixed bag, and red is flat out wrong. Overall, I did better than most past years with only having entirely blown it on four. Stay tuned later this week for my 2017 predictions,
