By Wesley j. Smith The progress on induced pluripotent stem cells continues. Until now, the only way to turn a skin cell into a stem cell was to use genes to “reprogram” the cell. Now, it has been done with chemicals in mouse studies. From the Nature story: Scientists have demonstrated a new way to …Continue reading "Induced Pluripotent Stem Cells without Added Genes"
By Dave Andrusko A report in today’s Guardian newspaper is just the latest evidence that when researchers are compelled to find stem cells sources other than human embryos, they benefit twice over. First, since human embryonic stem cells have no proven track record to date, resources are not wasted. Second, the need to look elsewhere …Continue reading "More evidence that when compelled to look elsewhere, scientists readily find acceptable alternatives to embryonic stem cells"
By Gerard M. Nadal Editor’s note. This first appeared at www.headlinebistro.com/en/columnists/nadal/index.html and is reprinted with permission. Dr. Nadal publishes frequently on his own blog at http://gerardnadal.com/ As soon as scientists begin discussing the differences between embryonic stem cells, adult stem cells, induced pluripotent stem cells, and altered nuclear transfer, most non-scientists become overwhelmed by the …Continue reading "Updating the Stem Cell Wars (Part I)"
