Effects of treatment with IL‐19 (10 ng·g−1·day−1) and IL‐19 blocking antibody (10 mg·kg−1·day−1) on angiogenesis in spinal cord of mice exposed to SCI. Graphs show the mRNA levels (n = 7) of three isoforms of VEGF (A, VEGF120, VEGF164, and VEGF188) in the injured spinal cords. In (B), Western blotting results and the corresponding quantification (B, n = 3) of PECAM‐1 are shown. VEGF‐A protein levels (C, n = 7) in spinal cord were determined by elisa. Data shown are the means ± SD. *P < 0.05, significantly different from the vehicle‐treated group; #P < 0.05, significantly different from the IL‐19‐treated group.
