ANGPT1 and myocardial infarction: Briefly, tissue perfusion, vessel density, and arteriolar formation improved.94 Ang1 and VEGF sustained dual delivery could result in an increase in cardiac muscle preservation, repair, myocardial function, and arteriogenesis in the acute MI rat’s model.95 In vitro research indicated that PDGF fibrin matrix-conjugated could enhance tissue regeneration in the ischemic flap model.
