ABSTRACT
Poor cell homing limits the efficacy of cardiac cellular therapy. The homing peptide, cysteine-arginine-glutamic acid-lysine-alanine (CREKA), targets fibrin effectively which is involved in the repair process of tissue injury. Here, we assessed if CREKA-modified stem cells had enhanced fibrin-mediated homing ability resulting in better functional recovery and structural preservation in a rat myocardial injury model. CREKA-modified mesenchymal stem cells (CREKA-MSCs) were obtained via membrane fusion with CREKA-modified liposomes. The fibrin targeting ability of CREKA-MSCs was examined both in vitro and in vivo. Under both static and flow conditions in vitro, CREKA significantly enhanced MSCs binding ability to fibrin clots (2.6- and 2.3-fold, respectively). CREKA-MSCs showed 6.5-fold higher accumulation than unmodified MSCs in injured rat myocardium one day after administration, resulting in better structural preservation and functional recovery. Fibrin is, therefore, a novel target for enhancing homing of transplanted cells to injured myocardium, and the delivery system of fibrin-targeting is on behalf of a universalizable platform technology for regenerative medicine.
