Researchers from the Hubrecht Institute have mapped the recovery of the heart after a heart attack with great detail. They found that heart muscle cells called cardiomyocytes play an important role in intracellular communication after a heart attack. The researchers documented their findings in a database that is accessible for scientists around the world. This brings the research field a step closer to the development of therapies for improved recovery after heart injury. The results were published in Communications Biology on the 29th of January.
