Figure Lengend Snippet: Fig. 3. Effect of RACs on vascular endothelial growth factor (VEGF) expression in peri-infarct area. Injection of both low (1 × 104 /50 µL) and high RACs (1 × 105 /50 µL) on day 3 after MCAO resulted in a significant increase in VEGF- positive cells in the peri-infarct area compared to PBS (*P < 0.05, Kruskal–Wallis test) [PBS: n=15, RACs (1 × 104 /50 µL): n=9, and RACs (1 × 105 /50 µL): n=10].

Article Snippet: Fixed sections were incubated in 5 mM hydrogen peroxide for 10 min before being exposed to 5% normal goat serum for an additional 10 min. Overnight incubation of the sections was carried out with polyclonal anti-goat VEGF (AF493NA; R&D Systems, Minneapolis, MN, USA) at a 50-fold dilution and monoclonal anti-rat IL-10 (ab33471; Abcam, Cambridge, UK) at a 200-fold dilution in a humidified chamber maintained at 4 °C.
