Key result
Boosting cardiac periostin levels in rats with myocardial infarction was associated with increased DNA synthesis by cardiomyocytes, enhanced angiogenesis, and improved cardiac function.
Why the study?
Does boosting cardiac periostin levels improve cardiac function and regeneration in rats with myocardial infarction?
Does boosting cardiac periostin levels improve cardiac function and regeneration in rats with myocardial infarction?
Boosting cardiac periostin in a rat model of myocardial infarction enhances myocardial repair, regeneration, and functional recovery.

Hypothesis-generating for periostin in post-MI regeneration; requires validation in larger models before any clinical consideration.
In rats with myocardial infarction, the boosting of levels of cardiac periostin — a matrix molecule derived from fibroblasts — was associated with increased DNA synthesis by cardiomyocytes, enhanced angiogenesis, and improved cardiac function.
