Experts'consensus on mammalian cardiomyocyte regeneration
Myocardial infarction(MI)leads to a massive loss of cardiomyocytes,resulting in pathological cardiac remodeling and heart failure.Promoting cardiomyocyte regeneration is crucial for repairing the damaged heart.It is acknowledged that regenerative cardiomyocyte derives from the existing cardiomyocytes.In recent years,advancements in this field have updated our understanding of cardiomyocyte regeneration in many aspects,including intrinsic cell source and microenvironmental characteristics,extrinsic factors,molecular biology mechanisms,and intervention strategies.Here,we report a consensus by an expert committee on the definition,characteristics,evaluation,research methods,regulatory mechanisms,and intervention measures related to mammalian cardiomyocyte regeneration.The aim is to clarify important unresolved issues in this field and to promote myocardial regeneration research and its clinical translation.
