Discovery in rat hearts could lead to tailored transplants

A few years back, I described induced pluripotent stem cells as "the holy grail." This is what stem cell researchers were looking for: a way to produce rejection-proof cells specifically tailored to the patient's system. However, stem cells still can't be grown into organs all by themselves -- we can make liver tissue but we can't make a liver. They need a frame upon which to grow.

And some guys from the University of Minnesota just found out how to get one.
