Do experimental treatments based on stem cells for stroke work and are they safe? We simply do not know yet. There’s hope for the future, but more data are needed. I’m still hoping to do a post with an update on the science in the next month or so, but have been busy with grants and papers. The animated show Family Guy weighed in on stem cells when main character Peter Griffin has a stroke that is then shown to be miraculously healed by …Read More

A brief report in the NEJM today highlights the risks facing patients who get stem cell treatment from dubious clinics as one such patient recently developed a large spinal tumor. Dr. Aaron L. Berkowitz and colleagues describe how this patient who received a mixture of several stem cell types from an overseas clinic was later diagnosed with a very unusual neoplastic growth on his spine. The data point to the tumor arising from the stem cell treatment as it was genetically distinct from the patient. …Read More

I wrote yesterday about two cases of science media hype on CRISPR and on stem cells for strokes. The latter case on stem cell hype stirred the most discussion and even some harsh words in the comments. As this stem cell stroke story on an encouraging but very small, preliminary study has unfolded across the mainstream and other media in the past 24 hours, a whole range of headlines for it have popped up. I’ve got a screenshot of a Google result for this …Read More

By Heather Main I recently attended the UCSD Health CIRM Alpha Stem Cell Clinics Network Symposium at the Sanford Consortium, San Diego. There was of course some great academic research presented, including conflicting views on liver stem cell compartments from Roel Nusse and David Brenner, and advances in CRISPR technologies from Matthew Porteus. However, what struck me about this meeting was how well it presented patient need and churned emotions outside the normal excitement or skepticism of an academic/basic science conference. Shirley Johnson is …Read More
