Update in 2020: It was kind of wild to read this post now so many years later as an “old” professor, seemingly ages from the realm of new PIs (principle investigators). What do you think? You can read more about the current state of our lab here. It’s an exciting feeling coming into a new lab as a new professor. An empty lab has so much potential and one can imagine how one’s lab will look in the future. I walked into my lab …Read More

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 in this paper by Yamanaka’s group, is extremely important and interesting. However there are several key open questions that remain. An important issue with this paper is the implication …Read More

Update in 2020: Wow, a lot has changed since this post almost 10 years ago, but Cell Stem Cell remains the main publisher of IPS cell articles still. The young iPSC field has published a truly massive number of papers in just 4 years. Searching ISI Web of Knowledge for papers with titles reflecting iPSC research (not just those that mention iPS cells), we find 424 total iPS cell articles from 2006-present. Interestingly, 32 of them (7.5%) were published in a single journal, Cell …Read More

Update in 2020: It seems now after all these years that the consensus in the now more mature field is that IPSCs and ESCs are nearly identical in most cases, and both have some of the same translational challenges such as teratoma-forming activity. It’s interesting to read this post from nearly 10 years ago and the concerns that were so intense back then. An important question in the young iPS cell field has been– just how similar these reprogrammed iPS cells are to embryonic …Read More
