Expression of PGIS in healthy and diseased tendon tissues. a Representative immunohistochemistry staining showing expression of IP receptor and PGIS in tendon tissues. Immunostaining (brown) nuclear counterstain is hematoxylin. Scale bar, 50 μm. b Representative confocal immunofluorescence images showing staining of cell nuclei (POPO1, cyan), CD31 (green), CD34 (red), and PGIS (purple) in diseased Achilles tendon tissues. Scale bar, 20 μm
