It happens several times a month these days. Some new, interesting paper comes out on IPS cells or on transdifferentiation. Immediately, opponents of ES cell research criminally twist the findings in the new paper and produce ‘news’ headlines that pop up high on Google to the effect that ES cells are now ‘obsolete’. IPS cells …
What is the best way to get new stem cell-based therapies to the millions of patients who need help? I would argue that this is the key question in the field of stem cell biology and regenerative medicine. Sometimes I think it is easy for folks to lose sight of that and fall into traps. …

It has been a rollercoaster few months between the anti-hESC court cases as well as Geron and Advanced Cell Technology (ACT) receiving the OK from the FDA to proceed with initial clinical trials of stem cell treatments. It’s OK to be excited about the clinical trials and I for one am, but we have to …

The trouble with the risk of teratoma presents a stem cell paradox. Stem cells possess two traits lacking in other cells: self-renewal and pluripotency. This duo of defining functions is key to the ability of stem cells to be used to treat patients via regenerative medicine. A paradox exists because while self-renewal and pluripotency are both …
If IPS cells are not ready for prime time, it is probably due to these three critical challenges for these amazing cells. TUMORIGENICITY Those of us who work with IPS cells are very excited about their potential for use in regenerative medicine therapies. One serious hurdle we have talked about in the past is tumorigenicity. …

We live in a plastic world, full of BPA. Over the last 1/2 century, the proportion of our food and beverages that are consumed out of plastic containers has skyrocketed. Unfortunately, the concentrations of plastic-related chemicals in people around the world, even in remote corners, has gone up in parallel. I’ve written about avoiding plastic …
Here an anonymous stem cell scientist frankly answers questions about the field in an interview with me. Of course I have to ask you about the recent U.S. court ruling essentially declaring all federal funding of human ES cell work illegal. What’s your take on this? ANSWER: The ruling has so many flaws in it. …

Regenerative medicine is very exciting. But what’s even better than regenerative medicine? Preventative medicine. If one can prevent a problem for occurring in the first place, it is far better than trying to treat it after the fact. Of course in many cases we do not know the causes of diseases so it is difficult …
A paper just came out in PNAS entitled “Promotion of direct reprogramming by transformation-deficient Myc“. The main thrust of this paper is that the tumorigenic and pluripotency-related functions of Myc could be separated. It focused primarily on the lesser studied LMyc. The topic of the intertwined good (pluripotency) and bad (tumorigenicity) functions of Myc, addressed …
