Histochemical evaluation of vascular endothelial growth factor in gastrocnemius muscle sections from Wistar rats, at the 4 experimental times (scale bar is 50 μm). Quantification of the number of CD31 positive cells/field: the graph shows the mean and standard deviation for each experimental variant. Statistical differences are marked: compared to the negative control group and compared to the ligation control group.
