Fig. 2

There were inflammatory differences between painful and pain-free rotator cuff tendons. Both the number of CD45 (pan-leucocyte marker) and CD206 (macrophage marker) positive cells were increased in the painful group versus the pain-free group. LDH expression was increased in the painful group, while VEGF was increased in the pain-free group. Photomicrographs depict the immunohistochemical staining of VEGF (a, e), LDH (b, f), CD45 (c, g), CD206 (d, h), in the painful and pain-free groups. Scale bars: 40 μm. LDH lactate dehydrogenase, VEGF vascular endothelial growth factor
