Figure 5From: Protease-activated receptors in the Achilles tendon–a potential explanation for the excessive pain signalling in tendinopathy PAR-3 expression in tendon tissue and cultured cells. Positive reactions for PAR-3 (red) shown in cultured tenocytes (A), tenocytes in biopsies (arrow in B), vessels (asterisk in C & D), as well as in nerve fibres (N in D). B & C are sections showing tendinosis, D is from a healthy tendon.Back to article page
