Prolonging the life of heart attack victims may become a reality for millions as scientists have successfully tested on mice a way to activate the regrowth of heart muscle. Human trials are expected to follow.
The combined effort of Australian and Israeli researchers at the Sydney Victor Change Cardiac Research Institute and the Weizmann Institute of Science has led to a regeneration of muscle cell numbers in the heart by as much as 45 percent.
Their research was published in the journal Nature Cell Biology.
The growth of cells was accelerated by “turbo-charging” a specific hormone called neuregulin, according to Sydney-based Professor Richard Harvey from the University of New South Wales.
