Figure 3

PAR-1 expression in tendon tissue and cultured cells. PAR-1 immunostaining (red) was not found in tenocytes (arrow) in either tissue sections from tendon biopsies (B) or in cultured cells (A). DAPI-combined-staining (blue) is shown in (A) to visualize cells without reactive staining for PAR-1. Any red staining in (A) and (B) is considered background staining and not specific reactions. Vessels (asterisk in C) and nerve fibres (N) in (D) were clearly reactive. B is a healthy tendon section, C & D are from tendinosis.
