Expression of fibroblast activation marker Podoplanin (PDPN) and nociceptive neuromodulator NMDAR-1 in diseased supraspinatus tendon tissues. a–b Representative immunofluorescence images showing staining of cell nuclei (POPO-1, cyan) and PDPN (green) with a expression of NMDAR-1 (red) and PGIS (violet) and b expression of TLR4 (red) and IL-1R (violet). c Representative confocal immunofluorescence images showing merged image of diseased tendon sections stained with isotype control antibodies for mouse IgG1, IgG2a, and IgG2b and rabbit IgG fractions. Cyan represents POPO-1 nuclear counterstain. Scale bar, 20 μm
