There have been a lot of recent headlines about a report that it might be possible to grow human organs in pigs. Someone even proposed the crazy idea of using human iPS cells to make chimeric human/swing animals that contain certain human organs, which could then be harvested. To say this is a bad idea […]

Two companies, Advanced Cell Technology (ACT) and Geron, both HQ’d here in California, have FDA-approved early stage clinical trials in the works. Geron’s trial has already started and reportedly now has enrolled at least two patients. The trial is of course for the safety of Geron’s GRNOPC1 oligodendrocyte product made from human ES cells for

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,

I’ve been lecturing on stem cells as a professor here at UC Davis School of Medicine for many years so I can answer common questions such as “What are stem cells?”. The medical students ask many great questions. They are always interested in clinical applications. The goal of today’s article is to help you have

There are a lot of myths in the stem cell field, some even embraced by some stem cell scientists such as the notion that teratoma are always benign. But when we start talking about translating stem cell technology into the clinic, to the bedside, it is especially important to cast aside our myths, no

A Federal Appeals Court ruled 2-1 today to overturn Judge Lamberth’s injunction against federal funding of ES cell research. Great news! You can read the decision here (warning: big pdf). A key part of the ruling was the following: “the plaintiffs are unlikely to prevail because Dickey-Wicker is ambiguous and the NIH seems reasonably to

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 Oklahoma State Legislature is reportedly poised to potentially pass an outright ban of ES cell research. While in the past similar legislation was vetoed by previous Oklahoma Governor, Democrat Brad Henry, current Republican Governor Mary Fallin is likely to sign the legislation. The Oklahoman newspaper website today contains a factually incorrect, inflammatory piece by

Last Fall’s mid-term election brought into office several new Republican Governors who during their campaigns used strong, anti-embryonic stem (ES) cell research rhetoric. For example, then candidate for Governor of Wisconsin, Scott Walker (now the Governor) used some of the strongest language, which was ironic considering that human ES cells were first produced in Wisconsin
