>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

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, 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

“Able to become all tissue types”

That’s the claim by Dr. Anthony Atala in an interview with Gwen Ifill of PBS. So these cells actually have been in the amniotic fluid for many years, and we’ve known about their presence for many years. The major finding in this study is the fact that we found a stem cell population that is … Continue reading

“Pluripotent” Amniotic/Placental Stem Cells

I’ve just skimmed the Nature Biotechnology article (free abstract and references with free registration to, the article is for subscription or by individual purchase, only)by Atala, De Coppi, et. al, “Isolation of amniotic stem cell lines with potential for therapy” (Nature Biotechnology – 25, 100 – 106 (2007). Published online: 7 January 2007; | … 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

How human is human-enough?

A group of very well respected scientists, philosophers and ethicists (all involved in bioethics and stem cell research) have joined together to discuss and draft what they call a “consensus” on stem cell research, both destructive embryonic stem cell research and non-destructive, ethical non-embryonic stem cell research. The document can be accessed at the Berman … Continue reading
