Allogeneic GFP^pos pPICs Stimulate Neoangiogenesis Following Transplantation Into Injured Skeletal Muscle

(A) Skeletal muscle cross sections were stained for vWF to evaluate capillary density, scale bar = 50 μm. (B) Number of capillaries per myofiber, determined from 5 fields of view per muscle, n = 5 animals per group. Data are mean ± SD, *p < 0.0001 versus uninjured. (C) Newly formed BrdU^pos/vWF^pos capillaries were identified 14 days post-injury, scale bar = 20 μm. (D) Percentage of BrdU^pos capillaries per total capillaries, determined from 5 fields of view per muscle, n = 5 animals per group. Data are mean ± SD, *p < 0.0001 versus CTX-PBS–treated. vWF = Von Willebrand factor; other abbreviations as in Figure 1.
