In several studies, the capillary number of skeletal muscle was reduced in diabetes (Kivela et al., 2006; Marin et al., 1994; Mathieu‐Costello et al., 2003; Sexton et al., 1994), which is expected since VEGF expression levels regulate capillary number (Liu et al., 2018). The gene discussed is VEGFA; the disease is diabetes mellitus.
