Bioengineered FSTL1 Patches Restore Cardiac Function Following Myocardial Infarction

Improving the limited ability of the heart to regenerate after infarction is crucial. Researchers now demonstrate that delivery of follistatin-like 1 (FSTL1) into injured hearts via collagen patches stimulates cardiomyocyte proliferation and cardiac functional recovery. These findings highlight the epicardium as a source of novel regenerative factors and biomimetic nanomaterials in cardiac translational medicine.
