Treatment with Sildenafil and Donepezil Improves Angiogenesis in Experimentally Induced Critical Limb Ischemia
Figure 5
Histochemical evaluation of dividing cells in gastrocnemius muscle sections from Wistar rats, at the 4 experimental times (scale bar is 50 μm). Quantification of the number of Ki-67 positive cells/field: the graph illustrates the mean and standard deviation for each experimental variant. Statistical differences are marked: compared to the negative control group, compared to the ligation control group, and compared to the sildenafil treated group.
