Figure 3 (A) The capillary density was significantly lower in the hypercholesterolemia (HC) group than in the control group in the ischemic hindlimb, which was restored in the HC + Folate group. In the nonischemic hindlimb, the capillary densities did not differ among the three groups. (B) Similarly, the capillary/muscle fiber ratio was significantly lower in the HC group than in the control group in the ischemic hindlimb, which was restored in the HC + Folate group. In the nonischemic hindlimb, the capillary/muscle fiber ratio did not differ among the three groups. n = 6 in each group; ***p < 0.001.
