Keeping up with Clinical Research with Human Embryonic Stem Cells

Unless one works daily in a specific area of biomedical research, it can be next to impossible to keep up with developments.  I have trouble keeping up with a reasonable amount of the progress in research for some cancers.  Trying to track stem cell research requires more bandwidth than I have.  Still, from time to time I do try to do at least a little... // Read More »

Direct cell reprogramming to grow a new organ and the ice bucket challenge

A recent article in The Guardian reports on an interview with Clare Blackburn of the Medical Research Council Centre for Regenerative Medicine at the University of Edinburgh where they have recently been able to induce a direct transformation of mouse skin fibroblasts into thymic epithelial cells. When these induced thymic epithelial cells were mixed with other thymus cell types and transplanted into mice they grew... // Read More »

The upcoming debate over “CIRM 2”–CORRECTION

(I made an error about a past video involving the late actor Christopher Reeve in my post yetsterday. I strongly implied, at least, that such a video was used in the 2004 campaign for passage of California Prop. 71.  That would not be correct.  The video in question, easily found on YouTube, was aired [it indicates there] by Nuveen Investments during the 2000 Super Bowl.... // Read More »

The Recent Stem Cell News

Last week’s edition of Nature includes developments in the world of stem cell research, also noted in the general press: First: A group from Portland, San Diego, and Stockholm published work (payment required to read article) seeking to define the “best” human pluripotent stem cells on cellular and molecular grounds.  They compared: Stem cells taken from an embryo, created in IVF and destroyed for the... // Read More »

Germline Alteration and Defining “Just Research”

Yesterday’s post by Steve Phillips raises a central question for us in the “biotech century”:  are there some sorts of experiments that fundamentally ought not be done because of the potential they will be grossly misapplied by bad actors?  Steve cited research by Lord Robert Winston seeking to create genetically altered pigs—that seem, from the description in the press, to be what scientists call “transgenic”... // Read More »

“Curb Your Enthusiasm” about Adult Stem Cells?

This week, Nature has an online news article and editorial about a new meta-analysis published in the British Medical Journal (BMJ).  The BMJ article addresses discrepancies in published reports of clinical trials of adult stem cells to treat patients with heart disease/heart failure.  For some time now, this has appeared to many to be a particularly promising use of adult stem cells. Well, not so... // Read More »

Last Week’s Stem Cell Cloning News

Readers of this blog probably saw last week’s report, as the NPR headline put it, that “First Embryonic Stem Cells Cloned from a Man’s Skin.”  I was able to read the full text of the online publication, by Cell Stem Cell, here. The stated goal of the work is to use somatic cell nuclear transfer (SCNT) to clone an embryo that can then be used... // Read More »

For diabetes, stem cell recipe offers new hope

Douglas Melton is as impatient as anyone for a cure for diabetes. His son developed the disease as an infant, and his daughter was diagnosed at age 14. For most of the past 2 decades, the developmental biologist at the Harvard Stem Cell Institute has focused his research on finding a cure.
