Stem Cells are thankfully a non-issue now.
But, President Bush was proven right. He drew a line...no federal funds for questionable results but with verified embryo death. Now, without federal funding, stem cells can be extracted from the placenta and amniotic fluid (discovered by an NC team) and of course, the recent "de-differentiation" of cells.
As of yet, said cells do not have the same potential for transformation or use as others, but they are certainly better than nothing.
