A groundbreaking discovery from Michigan State University has revealed that oxytocin— commonly known as the “love hormone”—may play a critical role in healing damaged human hearts. In this video, we break down a new study published in Frontiers in Cell and Developmental Biology, led by Dr. Aitor Aguirre, which shows that oxytocin can trigger heart regeneration by reprogramming cells in the heart’s outer layer into stem-like cells. These cells, called epicardium-derived progenitor cells (EpiPCs),
