>!Safe! Induced Pluripotent Stem Cells
>Robert Lanza is now reporting that his research group has produced induced Pluripotent Stem Cells (iPS) that are safe for use in humans. The website, Red Orbit, has provided a link to the original (.pdf)article. See the Time magazine news article, here. Lanza gives credit to the pioneering work of Shinya Yamanaka: Dr. Robert Lanza, … Continue reading
Study of iPS cells draws nearer to finding cures
Research in stem cells and the origin and treatment of disease is definitely moving away from destructive embryonic stem cell research toward induced pluripotent stem cells (iPS). A fantastic review that connects Japan’s Dr. Yamanaka, San Francisco’s Srivastava, the University of Texas Southwestern Medical Center in Dallas, and the Burnetts of Sulphur Springs, Texas, is … Continue reading
>Yamanaka has a conscience
> “When I saw the embryo, I suddenly realized there was such a small difference between it and my daughters,” said Dr. Yamanaka. The New York Times article on Shinya Yamanaka, “Risk taking is in his genes,” (free one time registration necessary) should get the headline-writer in trouble for a sad pun. Instead, Dr. Yamanaka … Continue reading
>Wash this reactionary’s mouth out with soap!
>Bioethics.net compares the Bush administration’s happiness about reprogrammed adult stem cells with that man, Mr. Clinton’s, “I did not have sex with that woman!” and President Bush’s statement “Mission accomplished,” after our US troops captured Baghdad. I’ll accept the latter (at some future date, if the evidence supports it), but the first is at least … Continue reading
Reactionary Scientists
I wonder how often our friend from Kyoto is planning to publish and what tweaks we’ll hear about next week? I also wonder how many of the comments about “must fund all” come from – or actually are a type of – the application of the sort of pressure that Gearhart told his audience in … Continue reading
>Wait ‘Till Next Week! (More iPS good news)
>Dr. Yamanaka of Japan, the MD who made history last week by announcing that he had been able to obtain embryo-like stem cells fom adult skin cells called fibrobalsts. On Friday, November 30, has published a new report in Nature Biotechnology telling us how he was able to skip inserting the potential cancer causing gene, … Continue reading
>Translation of Yamanaka, Yu "induced Pluripotent Stem Cells" (Revised)
>Scientists who report their findings are expected to discuss the problems as well as the outcome of their research. This is usually found in the “Discussion,” “Conclusions” or “Results” section of the paper. This is the best place to figure out what the researches intended, what they did and what the report means. (Then you … Continue reading
>Biographic article on Yamanaka
>Here’s a cute biography of Shinya Yamanaka, lead researcher from the Japanese team that reported reprogramming of adult cells into embryonic-like stem cells. As an M.D. myself, I find it interesting that, unlike veterinarians James Thomson of Wisconsin and Time Magazine Person of the Year, Hu Suk Hwang, Dr. Yamanaka is a human doctor, trained … Continue reading
>Translating Thomson’s “Induced Pluripotent Stem Cell Lines Derived from Human Somatic Cells”
>Yu, Thomson, and all, from Wisconsin published their paper on reprogrammed induced Pluripotent Stem (iPS) cells from adult cells online in Science Express online, yesterday, just after the Yamanaka/Takahashi team from Japan published theirs in the journal, Cell. (The Thomson paper was not scheduled to go live online until the 22nd.) As discussed on this … Continue reading
>Science Magazine on "Race" to Stem Cell Breakthrough
>The Thomson article is online (abstract is free, article is behind a pay wall), but I haven’t had a chance to read it. In the meantime, Science Magazine has a news article on both the publication from Wisconsin’s Thomson and the previously discussed Takahashi/Yamanaka article in Cell. Be sure and read the last sentence!!!! Now … Continue reading
