ILK overexpression in EPCs in vitro. (A) EPCs in bright field and the same dark field. Most of the early EPC in UMT+ILK group were labeled with red fluorescence. (B) mRNA level of ILK in the EPCs of three groups after transfection. (C) Densitometric analysis of ILK and VEGF protein relative to β-actin protein in three groups. (D) Representative western immunoblotting showing ILK and VEGF protein expression in control, UMT+empty plasmid, and UMT+ILK groups *p<0.05 versus control and empty plasmid group. UMT, ultrasonic microbubble technique.
