Images and quantification of CD206 (mannose receptor) immunopositive (+) macrophages (stained red) in forearm tissues. a-d CD206+ cells in longitudinal sections of median nerves at the level of the wrist. e The number of CD206+ cells per mm2 in the median nerve at the level of the wrist. f-i CD206+ cells in cross-sections of mid-forearm regions of flexor digitorum muscles. j The number of CD206+ cells per mm2 in flexor digitorum muscles, in cross-sectional mid-forearm regions. k-n CD206+ in longitudinal sections of flexor digitorum tendons. o The number of CD206+ cells per mm2 in flexor digitorum tendon, in mid- to distal regions. Abbreviations: ct = connective tissue, epi = epineurium in nerves and epitendon in tendons; N = median nerve, T = tendon. Scale bar in panels a, f and k = 100 μm and applies to all other panels. Symbols in e, j and o **: p < 0.01, compared to TASK-Tx group; &: p < 0.05 and &&: p < 0.01, compared to a control group as shown. Mean ± 95% CI shown
