Adult stem cell lies - everything old is new again - The Diigo Meta page

  It's come time to lie about science again - this time about the reality of embryonic stem cell pluripotency - and some of the old lies are coming back out of the storage shed. For instance, Andrew Breitbart on Real Time last night, and in a video from (liar for Jesus) Tony Perkins of the Family Research Council, I've heard about how adult stem cells have cured or treated 72 diseases. Oh and embryonic stem cells, they've cured none. It's been a while since we've seen this adult stem cell nonsense. (denialism blog)

  • However, while these cells are great at doing their job, the issue with adult stem cell research is, can they do another stem cell's job? That is, instead of making just blood, could a hematopoietic stem cell make, say, an insulin secreting pancreatic cell? The answer, despite some initial promising results around 2001, is no.
  • the true state of the field is that with the exception of hematopoietic stem cell transplant to replace bone marrow, adult stem cells are no farther along in application to human disease than ES cells are - they are in a purely experimental stage.
  • Embryonic stem cells are so promising because they don't just make one type of cell or cells from one of the three tissue layers. By definition, they can make every type of cell in the body.
