The aim of this study was to determine the characteristic differences in tendinocytes derived from tendons in the equine forelimb, superficial digital flexor tendon (SDFT), deep digital flexor tendon (DDFT) and common digital extensor tendon (CDET), in morphology, proliferation, collagen production ability and ability for synthesis of matrix metalloproteinases (MMPs). Significant differences were observed in cell number in vivo. The cellular number was largest in the SDFT and smallest in the CDET. The values of in vitro proliferation ratios and ability for synthesis of collagen and MMPs were largest in the SDFT and smallest in the CDET. Addition of TNFalpha to culture of all three types of tendinocytes increased the synthesis of both proMMP-9 (except CDET) and collagen and decreased proMMP-13 synthesis and had no effect on proMMP-2 synthesis. Flexor tendons in forelimbs (SDFT and DDFT) restore energy during locomotion and are more easily injured than are extensor tendons. This structural property would cause active ECM and MMPs synthesis. And CDET have very low turnover potential; in the small number of cells, low cellular proliferation, lower ability for synthesis of collagen and MMPs. The isolated tendinocytes provided much information on the characteristics and properties of tendons for the ECM turnover system and responsiveness of tendinocytes to complex inflammatory responses in tendinopathy.
