ScienceShanghai, Hong Kong researchers unlock key heart repair mechanism

A joint Shanghai-Hong Kong team published a study in Science showing that, when major cardiac arteries are blocked during a heart attack, tiny capillaries can be reprogrammed into functional collateral arteries. The finding could support therapies that stimulate the heart to build new blood-supply networks for acute myocardial infarction and other ischemic heart diseases.
