In a rather nice Technology Review piece, David Ewing Duncan takes an in-depth look at cardiomyocytes grown from induced pluripotent stem cells that were created by "reprograming" his blood cells - all in an effort to understand his risk for disease. The piece also mentions Stanford cardiologist Euan Ashley, MD, who looks at Duncan's cells and:
. . .verified my persistent normalcy - and confirmed that the cells in question were what they were supposed to be. "These tests prove that the cells are cardiomyocytes," [Ashley] said, "which at this early stage in this science is important."
The rest of Duncan's inquiry is quite interesting and worth reading.
