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 …

GROWING HUMAN LIVER TISSUE FROM IPS CELLS

By David Prentice and Andrew Mullins Editor’s note. iPS cells (induced pluripotent stem cells) are made by adding a few genes to a normal cell such as a skin cell, causing the normal cell to look and act like an embryonic stem cell, yet without use of embryos, eggs, or cloning technology. They are not …

A Peak of Reality at the World Stem Cell Summit

By David Prentice This year the World Stem Cell Summit was held in West Palm Beach, Florida.  It’s an annual event originally intended to hype the “potential” of embryonic stem cells to cure all known maladies. It was started years ago and continues to be promoted by some of the leading cheerleaders for embryonic stem …

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 …
