The paper:
M. Laflamme et al., “Cardiomyocytes derived from human embryonic stem cells in pro-survival factors enhance function of infarcted rat hearts,” Nat Biotech, 25:993–94, 2007. (Cited in 140 papers)
The finding:
Charles Murry and his colleagues at the University of Washington demonstrated that cardiomyocytes derived from human embryonic stem cells (hESCs) can help repair an infarcted rat heart. Murry’s team developed a novel protocol to guide all the hESCs to differentiate into cardiomyocytes, then exposed the cells to a prosurvival cocktail (PSC). “Our method worked 50-fold better than previous efforts at forming cardiac muscle,” says Murry. Ten percent of these cardiomyocytes survived, where none had survived in previous experiments.
The impact:
“This is the first study to demonstrate improved function following an infarct,” Dan Rodgers, a molecular biologist at the University of California, Berkeley, writes in an email.
The details: To ensure hESCs differentiated into mature cardiomyocytes, the team ...
