Figure 4From: Protease-activated receptors in the Achilles tendon–a potential explanation for the excessive pain signalling in tendinopathy PAR-2 expression in tendon tissue and cultured cells. Positive immunostaining for PAR-2 (red) in cultured tenocytes (A) vessels (asterisk in C & D), and nerve fibres (N in D), as well as in tendon biopsies (arrow in B). All sections (B-D) are from healthy tendons.Back to article page
