>"Fertilized eggs" and cloned human embryos (The future, again)

>“ScienceBlogs” is one of the examples I give when I’m trying to explain the anti-life, anti-religion atmosphere that is pushed (like a religion itself) in our universities and by the Powers That Be in science academia and publishing. I think I may have identified one or two of the bloggers as believers (proof that miracles … Continue reading

>Buy "Yamanaka StemCell Factors"

>No, Really!!! Your “Plasmid Cart” is empty! I’m studying up to be able to answer some very tough questions by Lydia from an earlier post. While “Googling” “Oct 3/4,” I found this ad, for “Yamanaka StemCell Factors.” as sold by “www.addgene.com.” Addgene.com is selling the plasmids mentioned in Takahashi and Yamanaka’s “Induction of pluripotent stem … Continue reading

>More Questions on Embryonic Stem Cells

>Lydia asked about my comments on embryonic-like cells derived from umbilical cord blood. Umbilical cord blood itself appears to be at least multipotent. However, Texan and British researchers worked with NASA to produce “embryonic-like” stem cells by manipulating them with filters and a special centrifuge. Here’s my post from August, 2005 on those cells. And … Continue reading

>New Stem Cells Questions and Answers

>A reader posts some questions that I’ll try to answer. (Thanks, Janet!) The most important thing to remember is that the new iPS cells appear to be like embryonic stem cells, but they can be made without killing anyone and they can be made to match the patient. “Does this new procedure use any cells … Continue reading

“George Bush and the Catholic Church hold us in thrall”

That’s what Terry over at the Womens Bioethics Project Blog says. Terry has a big problem with the breakthrough in stem cell research that so many of us are thrilled with, and says, It is amazing to see how the Catholic Church and George Bush can hold us all in thrall regarding human embryonic stem … Continue reading

>Thousands of Researchers Now Jobless

>I don’t think that the Scientific Activist (“Reporting from the Crossroads of Science and Politics”) is at all happy with the “framing” of the reports on the reprogrammed adult stem cells. (beware the language) However, I did learn where some of the speculation about iPS cells being “like an embryo.” may have come from. “Activist” … Continue reading

>Thomson framed: "iPS more relevant than embryonic"

>Framing Science has a great quote from James Thomson, whose lab announced that they had proven a way to reprogram adult cells to become more primitive, embryonic-like stem cells, called “induced Pluripotent Cells.” I don’t know how I missed this one yesterday: “. . . says Thomson, the scientist who in 1998 isolated stem cells … 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

On the power of Naming (iPS and Art Caplan’s Off the Wall Question)

Art Caplan, Ph.D., is one of the pseudoeditors over at the Journal of American Bioethics blog, bioethics.net and a founding member of the “Progressive Bioethics Initiative,” along with Robin Alta Charo, the subject of one of yesterday’s posts. Dr. Caplan writes a regular “Breaking Bioethics” column for MSNBC. Art took the liberty of renaming the … 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
