Induced Pluripotent Stem Cells without Added Genes

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 …

More evidence that when compelled to look elsewhere, scientists readily find acceptable alternatives to embryonic stem cells

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 …

Updating the Stem Cell Wars (Part I)

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 …
