Yamanaka may have found a way to give exogenous Myc the boot from the iPS cell universe. It has always been a frustration in the iPS cell field that Myc, a proto-oncogene, is so important for reprogramming. Yes, you can make iPS cells (especially mouse) without Myc, but it can be orders of magnitude harder, […]

The best talk today was the keynote address by Dr. George Daley focused mostly on iPS cells. Dr. Daley is one of the world’s experts on iPS cells and pluripotent stem cells more generally. He covered many interesting elements of the iPS cell field including the genetic mutations that seem to occur during the reprogramming

Yesterday I ran a cancer stem cells meeting here at UC Davis School of Medicine. We had some great speakers and over 150 participants including our outstanding keynote speaker, Dr. Jeremy Rich, Director of Stem Cell Research at the Cleveland Clinic. One of the ideas percolating through the meeting was that during cancer development, there

Six months ago, I published a Top 10 list of questions and predictions for the stem cell field. How did I do? A mixed bag. Below are the questions and predictions from October 2010 (in blue), along with an update as to how my predictions fared. 1) How will Geron’s Phase I Clinical Trial go?

How are things looking for the stem cell field for Spring 2011? Issue One. Getting to the clinic. At this point, Geron and ACT have their FDA-approved clinical trials underway using derivatives of human embryonic stem cells. As expected no news has leaked out on how things are going and it may well be Fall

Just how tumorigenic are iPS cells? The field really doesn’t know at this point. However, a steady stream of papers have raised red flag after red flag about genomic and epigenomic alterations/mutations that are linked to cancer. Of course, then there is the fact that all the genetic changes actually used to make reprogrammed cells

It’s been more than 4 years since Shinya Yamanaka published the remarkable finding that his lab could transform or “reprogram” regular cells called fibroblasts into a very unique state that was quite similar to that of embryonic stem cells (ESC). Yamanaka called these new cells “iPS cells” for induced pluripotent stem cells. iPS cells Since

Could iPS cells replace ES cells? A new paper is out from a team at The Salk lead by Joseph Ecker that the methylomes of many different human iPS cells. Their conclusion is that while iPS cells and ES cells are generally very similar in terms of the global portions of the genomes that are

It has been an eventful year so far for the stem cell field. Where do we go from here ? What are the key questions that face the field? Below are my top 10 questions for the field, NOT listed in any particular order, and some predictions. Update: you can see the predictions for the

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
