This was exciting to read:
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.
And here 's a big part of what makes it so great:
The creation of iPS cells from adult cells sidesteps ethical concerns associated with the use of embryonic stem cells, and allows the generation of stem cells matched to a patient's own immune system, avoiding the problem of tissue rejection.
