Cardiac pericytes induce vasoconstriction after myocardial ischemia.

Pericytes are present surrounding the vasculature of the heart. The study of O'Farrell and colleagues now suggests a novel role for pericytes in the vasculature of infarcted hearts [9]. Cardiac pericytes induce blood vessel constriction post-ischemia, which is reversed by adenosine delivery. Future studies will reveal in detail the cellular and molecular mechanisms involved in this process in the tissue microenvironment in the heart.
