Double triumph in stem cell quest

...em compatible with the donor's immune system. The biggest question, though, is whether the stembrids really are true ESCs. Verlinsky says the cells express a number of ESC markers. His team has also shown the cells can differentiate into a number of cell types, including heart muscle cells, neurons and bloo...
