“It’s another fascinating twist on the story of how the heart can maintain and repair itself long term,” said University of Wisconsin, Madison, stem cell biologist Tim Kamp, who was not involved in the study. “They make a strong case that these [cells] are resident within the heart, and are poised to do the ...
