What Role Do Stem Cells Play in Heart Regeneration?

Stem cells are a critical component of heart regeneration research. Both endogenous cardiac stem cells and exogenous stem cells, such as those derived from bone marrow or induced pluripotent stem cells, have shown potential in promoting heart repair. These cells can differentiate into cardiomyocytes, endothelial cells, and other cardiac cell types, contributing to tissue regeneration. However, the efficiency and safety of stem cell-based therapies are still under investigation.
