Scientists have made really rapid progress in reprogramming adult tissue in the last couple of years.


A major step in making better stem cells from adult tissue

October 18, 2009 -- A team led by scientists from The Scripps Research Institute has developed a method that dramatically improves the efficiency of creating stem cells from human adult tissue, without the use of embryonic cells. The research makes great strides in addressing a major practical challenge in the development of stem-cell-based medicine.

The findings were published in an advance, online issue of the journal Nature Methods on October 18, 2009.

The new technique, which uses three small drug-like chemicals, is 200 times more efficient and twice as fast as conventional methods for transforming adult human cells into stem cells (in this case called "induced pluripotent stem cells" or "iPS cells").

wow, impressive but I still don't like the use of chemicals.
