Increased homing and paracrine signaling of preconditioned dmMSCs. (A, B) Increased homing of preconditioned dmMSCs compared with nontreated MSCs along with corresponding quantification in (C); Scale bar about 20 μm. (D) Gene-expression analysis of paracrine factors in all animal groups by using quantitative real-time PCR. (E) Gene-expression analysis in hearts from all animal groups. (F) Gel quantification using image J. Group II versus group III, *P < 0.05; **P < 0.01, and ***P < 0.001; group II versus group IV, ^#P < 0.05; ^##P < 0.01; and ^###P < 0.001; group III versus group IV, ^φP < 0.05; ^φφP < 0.01; and ^φφφP < 0.001.
