FIG. 2.

Adeno-associated virus (AAV) vector expression was determined from the lesion epicenter at 56 days post-injury. (A) Expression of vascular endothelial growth factor-165 (VEGF₁₆₅), showing a significant increase in all AAV-treated groups compared to AAV-LacZ viral controls. Error bars represent standard deviations (*p = 0.0009). (B) Expression of angiopoietin-1 (Ang-1), indicating a significant increase in the AAV-VEGF₁₆₅- and AAV-Ang-1-treated groups. Error bars represent standard deviations (*p = 0.0206). (C) Expression levels of Iba-1, a marker for microglia. No significant difference was observed between treatment groups. Error bars represent standard deviations. (D) β-Actin expression to ensure equal concentration of protein loading. No significant differences were observed between groups. Error bars represent standard deviations.
