Adult humans fail to regenerate their hearts following injury, and this failure to regenerate
myocardium is a leading cause of heart failure and death worldwide. Although all adult
mammals appear to lack significant cardiac regeneration potential, some vertebrates can
regenerate myocardium throughout life. In addition, new studies indicate that mammals have
cardiac regeneration potential during development and very soon after birth. The

Adult humans fail to regenerate their hearts following injury, and this failure to regenerate myocardium is a leading cause of heart failure and death worldwide. Although all adult mammals appear to lack significant cardiac regeneration potential, some vertebrates can regenerate myocardium throughout life. In addition, new studies indicate that mammals have cardiac regeneration potential during development and very soon after birth. The mechanisms of heart regeneration among model organisms, including neonatal mice, appear remarkably similar. Orchestrated waves of inflammation, matrix deposition and remodeling, and cardiomyocyte proliferation are commonly seen in heart regeneration models. Understanding why adult mammals develop extensive scarring instead of regeneration is a crucial goal for regenerative biology.
