The expression of VEGF-A in correlation with PPARγ and BCL-2. a Representative sections co-labeled for PPARγ (green) and VEGF-A (red) and b the quantification analysis. c Negative correlation between PPARγ and VEGF-A expression. d Representative sections co-labeled for VEGF-A (red) and BCL-2 (green) and e the quantification analysis. f Positive correlation between VEGF-A and BCL-2. Scale bar, 50 μm. Each bar represents the mean ± SD. Results are representative of three independent experiments. *p < 0.05, #p < 0.001
