>Genes Cut Out of Reprogrammed Cells

>Lots of people (here, here, and here, etc.) are commenting on the “Proof of Concept” by Jaenisch, et. al., in this week’s ScienceExpress (early online publication before print) that showed gene modification to reprogram mouse cells in order to create blood line stem cells that would achieve gene therapy – or even, a cure – … Continue reading

>Flash: Embryonic tissue more difficult to obtain than adult

> This could liberate future researchers from relying on embryonic tissue, which can be more difficult to acquire. “NatureNews,” the news alert website for the journal Nature, has a news report (registration required) on a study published in the December 6 issue of the journal by researchers from Bonn, New York, Rhode Island, and Pennsylvania … 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

>Knee Jerk Deceit (Embryonic Stem Cells)

>The Washington Post has published an editorial by Alan I Leshner, Ph.D., and James A. Thomson, Ph.D. The op-ed is evidently in reaction primarily to Charles Krauthammer’s November 30, 2007 column and blurs the line between fact and fiction in order to make a political plea to remove restrictions on funding for embryonic stem cell … Continue reading

>"embryo uber alles"

>Ellen Goodman reminds us that it ain’t over yet. As she said in her November 20, 2007 op-ed piece (Free registration at the Boston Globe may be necessary), Democrats, on the other hand, may breathe a sigh of regret. The stem-cell controversy gave pro-choicers an iconic image of their enemy: someone who put the embryo … 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

>Germans Praise Stem Cell Breakthrough

>It turns out that it’s not just American Christian right-wingers who are grateful that there’s an alternative to embryonic stem cells from the destruction of human embryos. Japanese scientist Shinya Yamanaka wins top German cancer prize Heidelberg, Germany (dpa) – Shinya Yamanaka, the Japanese scientist who last week revealed a revolutionary new technique to manufacture … 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
