>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
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
“I want” ethics reigns, even with good stem cell news
I found someone willing to admit that she’s not happy with today’s news on the production of embryo-like stem cells without the destruction of embryos or harm to women from donating eggs. Robin Alta Charo is a lawyer who, as part of the Clinton administration’s National Bioethics Advisory Commission, helped fabricate the policy to allow … Continue reading

We need sharing, not eggs or embryos!
From WebMD: “We don’t need any eggs or embryos at all,” says Shinya Yamanaka, MD, a professor at the Institute for Frontier Medical Sciences in Kyoto, Japan. Yamanaka describes his lab’s early successes in mice creating stem cells from adult cells. His research involves isolating two dozen chemicals that give embryonic stem cells their ability … Continue reading
