Therapeutic effect of MRSP on apoptosis after balloon injury in vivo. A Representative microphotograph of HE staining in different groups at one or two weeks after balloon injury, and analysis of the intima area, media area, I/M ratio and lumen area. B Quantification of apoptosis performed at day 7 by TUNEL staining in different groups. n = 6 for each group. *p < 0.05, **p < 0.01 vs. the model group
