Abstract
- The purpose of this study was to delineate the pattern of sympathetic innervation in the suprasesamoidean region of the deep digital flexor tendon (DDFT) in horses using immunohistochemical staining (IHC) for tyrosine hydroxylase (TH) and alpha-1 adrenergic receptor (α1-AR). Fourteen forelimbs were collected from 10 horses. Longitudinal sections of the suprasesamoidean region of healthy DDFTs were harvested. Most of the sympathetic innervation was found to be in the walls of blood vessels. The tendon tissue proper was sparsely innervated, with a lesser degree of innervation within the dorsal fibrocartilage. Increased α1-AR immunostaining was also detected in walls of blood vessels and in spindle cells of fibrocartilage. Both α1-AR and TH immunostaining were detected in tenocytes. These findings support the presence of autocrine/paracrine catecholaminergic signalling in equine tendon tissue.<br /> (Copyright © 2015 Elsevier Ltd. All rights reserved.)
