Genetic therapy heals damage caused by heart attack

Therapy with microRNA stimulates cardiac regeneration after a heart attack. Upper left, pig heart showing planes for cardiac magnetic resonance imagining (MRI). Upper right: MRI images at plane 3 of two pig hearts, one treated and one control, at 1, 4 and 8 weeks after infarction. The infarcted area is in red. Lower left: swine cardiac myocytes (green) with blue nuclei, connected through electrical junctions (red). Lower right: proliferating pig cardiomyocytes (green) in response to the microRNA (proliferating nuclei in pink)
