The chemical oxytocin, also called cuddle hormone or love hormone released when people engage in warm and loving activities like hugging, stroking, breastfeeding a child, and physical relations.
Oxytocin, a hormone connected with bonding and love, could help to heal damage following a heart attack. Researchers found oxytocin stimulates stem cells from the heart's outer layer and migrates into the middle layer where it develops into muscle cells that generate heart contractions. This could be used to promote the regeneration of heart cells following a heart attack.

A study revealed that the neurohormone oxytocin induces epicardial cell proliferation, which is vital in forming Epicardium-derived Progenitor Cells (EpiPCs).
Researchers show that, in zebrafish and human cell cultures, oxytocin has an unsuspected function: it stimulates stem cells derived from the heart’s outer layer (epicardium) to migrate into its middle layer (myocardium) and there develop into cardiomyocytes, muscle cells that generate heart contractions.
