Figure 6:

(A) Representative photomicrographs of neutrophils and neutrophil density expressed as the number of MPO-positive cells per mm² of muscle in WT (white) and Fgf2−/− (black) sham and ischemic skeletal muscles after 3 days of ischemia. (B) Representative photomicrographs of of total macrophages (Mac-3 positive) and total macrophage density expressed as the number of Mac-3-positive cells per mm² of muscle in WT (white) and Fgf2−/− (black) sham and ischemic skeletal muscles after 3 or 7 days of ischemia. (C) Representative photomicrographs of M2a (CD206-positive) macrophages and M2a macrophage density expressed as the number of CD206-positive cells per mm² of muscle in WT (white) and Fgf2−/− (black) ischemic skeletal muscles after 3 or 7 days of ischemia. Data are presented as mean ± SEM, n=4. *p<0.05 vs. Sham cohort, #p<0.05 vs. WT. Arrowheads (immune-positive cells). Scale bar: 10μm
