What happens for patients and clinics after a stem cell facelift gone wrong? What about other cell injection problems? Cell therapies raise new challenges and risks. You can stop taking a pill or an injection treatment. However, you can’t stop or retract stem cell treatments if there’s a bad side effect. Unlike other kinds of …

In the past year there has been a great deal of attention given to the potential use of CRISPR-Cas9 for gene editing in human embryos. An important recent development, described in a new NPR article by Rob Stein, is the use of CRISPR-Cas9 in healthy human embryos for developmental biology research by assistant professor Fredrik …

Here is a hub for 2017 stem cell and regenerative medicine meetings. If you do not see your meeting, please let me know and I will include it. Change– I’m also going to be listing online courses (in red) this year. This list is meant to be as inclusive as possible, but by listing specific …
The FDA issued a warning letter not long ago to Amniotic Therapies, LLC, a supplier of amniotic products including to one or more stem cell clinics, but now a federal judge in Texas has reportedly mostly blocked the FDA action in terms of the shutdown. The law firm representing Amniotic also issued a PR about the …

Last year I heard from several sources that there somewhere between 3-5 unpublished manuscripts reporting the use of CRISPR gene targeting in human embryos being shopped around at various journals in addition to the one that had been published. Since that time we’ve seen a grand total of one additional paper reporting on CRISPR of human …

An elderly woman in Australia reportedly died shortly after receiving a fat stem cell transplant. Sheila Drysdale passed away hours after getting an adipose stem cell treatment a few days before Christmas in 2013. That death is now being investigated by the coroner there. Not only is this death in Sydney distressing in it of …

I talked last year about human genetic modification by CRISPR with George Church a year ago. Now we’ve followed up with a long chat on this topic going into much more detail and with questions on recent developments. Each question is listed numerically and then there is a back and forth on that question with George …

Stem cell clinics are spreading like wild-fire across the U.S. A few months back the Sacramento area got a new stem cell clinic selling amniotic stem cell therapies for a variety of ills including most prominently arthritis and pain. This clinic is called Nervana Stem Cell Center. I first noticed it via a huge ad …

One of the difficult things about the regulatory sphere that covers stem cells in the US is that many aspects are confusing or puzzling both to the public and so-called experts. We’ve been talking through some of the questions that come up in this area in posts and comments on this blog. What does a warning …

I blogged recently about how Sacramento has a new stem cell clinic using amniotic stem cells called Nervana Stem Cell Center. Its website currently offers no details on the people behind the company that I could find. I sent Nervana a message on their website to try to learn more based in part on a commenter on …
