Story summary

Researchers confirmed that human heart muscle cells increase mitosis after a heart attack.
Dr. Robert Hume’s team at Sydney’s Royal Prince Alfred Hospital used Professors Paul Bannon and Sean Lal’s sampling method to collect heart sections, build a tissue model and identify regeneration proteins.
With cardiovascular disease causing 24 percent of Australian deaths and only ~115 transplants for 144,000 heart-failure patients, the findings suggest regenerative therapy could fill a treatment gap.
