What are iPS cells? We talk about iPS cells all the time. We are very excited about them. Heck, the web address for this blog is ipscell.com. But what are iPS cells, really? A simple definition of iPS cells is the following: Embryonic stem cell-like cells that are made from non-stem cells in a lab. …
The tragic 9.0 earthquake and tsunamis that hit Japan a few weeks ago are having lasting consequences not only for Japan, but also for the world via radiation. One area of particular concern is the radiation that has leaked and is continuing to leak from the damaged nuclear reactors. At this point, the radiation …

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 …
Each year brings more evidence that what causes many cancers is a case of biological betrayal on the part of stem cells via cancer stem cells. I have blogged before about the potential for stem cell-based regenerative medicine therapies to aid cancer patients. I have also written before about my own experiences as a cancer …
Last night President Obama gave a state of the union speech. He seemed appropriately somber given the many issues facing the country. One issue of particular importance is the federal budget and the deficit. Will Obama strongly get behind biomedical research and request budget increases for 2011 for NIH and NSF? If not, then the …
Yesterday I wrote about how difficult it is to tell different cell lines apart, including normal stem cells and cancer stem cells, especially since some accumulate accumulate oncogenic mutations that may make them seem more similar. A new paper is coming out that makes this case on a genomic level. Tomorrow’s Cell Stem Cell edition …

In this post I give my most interesting predictions about events in the stem cell field in 2011. Update: I’ve continuing doing predictions every year all the way through 2020 and intend to continue. See my 2012-2020 predictions here. Appeals court rules in favor of federally funded hESC research. This is more of a hope …
Advanced Cell Technology (ACT) announced that the FDA has approved their second human ES cell-based clinical trial, a combined Phase I/II, for the treatment of blindness. As a result, soon ACT will have two active, human ES cell-based clinical trials, both using the same human ES cell-based drug. The aim of the 2nd trial is …

As the year comes to a close this week, it is a good time to look back on 2010 and consider the major events in the stem cell field and give out awards. Stem Cell Event of the Year. I would give this award as a dual prize to Geron and Advanced Cell Technology (ACT) …
My lab studies iPS cells. We are excited about iPS cells and they have enormous potential. However, there are some realities about iPS cells related to safety that impede our ability to use them to treat patients any time soon. We must solve these roadblocks before we can move forward, but interestingly, these facts are …
