PTS promotes angiogenesis factor expression in ischemic lateral cortical tissue. PTS promotes angiogenesis factor expression in ischemic lateral cortical tissue at different time points. The mRNA levels of VEGF (a), Ang-1 (b), VEGFR2 (c), Tie-2 (d), CD31 (e), and α-SMA (f) were determined by real-time PCR at 1, 3, 7, and 14 days after MCAO. Data are presented as the mean ± SEM, #P < 0.05 versus Sham group; *P < 0.05, **P < 0.01 versus Veh group. n = 6 per group. g The protein levels of VEGF and Ang-1 were measured by western blotting. (h-i) Quantitative analysis of VEGF and Ang-1 expression. #P < 0.05 versus Sham group; *P < 0.05 versus Veh group. n = 6 per group
