Stem Cell Breakthrough

Seen this? The most interesting line (no stem cell pun intended) to me is the last one in the sample I'll quote you. The AP's take is virtually the same as this morning's W. Post headline. Why is this same observation --namely, that this could render the use of embryos unnecessary for stem cell research-- not made about adult stem cell research and cures do you suppose?
WASHINGTON — Harvard scientists announced they've discovered a way to fuse adult skin cells with embryonic stem cells (search), a promising breakthrough that could lead to the creation of useful stem cells without first having to create and destroy human embryos. The scientists said they were able to show in their early research that the fused cell "was reprogrammed to its embryonic state." Such a breakthrough could have the effect of taming a biting national debate about the ethics of stem-cell research, but not any time soon.
