Scientists at the University of Washington have used human embryonic stem cells to regrow rat heart tissue. This is an area where adult stem cells have failed completely. It's a great article to read, outlining the challenges they've previously dealt with and how they've overcome them.
If they could perfect this procedure, it might find another purpose for the 400,000 or so frozen embryos that are not adopted won't be thawed and tossed. However, even if that won't work due to political considerations, the interesting thing is that the scientists were able to pull this off with one of the "presidential line" of cells.
