Scientist have discovered a way to make embryonic (as opposed to pluripotent) stem cells from a patient's own white blood cells. Per the article:
Not only is the approach faster and far cheaper than current methods, but it eliminates the controversy surrounding embryonic stem cell research, which requires the destruction of an embryo, raising ethical concerns. The new approach also avoids the genetic risks associated with the alternative to the embryonic method, called induced pluripotent stem (iPS) cells. That technique requires the introduction of genetic material into a cell, and has lead to tumor growth in some cases....The researchers reported their results in this weeks journal of Nature.
The procedure seems to work in mice but has not been tested in humans.
