Interesting that the umbilical stem cells, which can be harvested without harming the child, appear to be more useful than embryonic stem cells, which reqire the destruction of the embryo.
Since the whole debate over the use of embryonic stem cells is a proxy debate over abortion, I expect this news will not get major play in the MSM.
It may be reported, but will likely be followed up immediately with a report on the 'exciting possibilities' of embryonic stem cell research.
