[Tenocytes and the extracellular matrix : a reciprocal relationship].
The characteristic cells in tendons and ligaments are called tenocytes, which are responsible for the formation and turnover of the extracellular matrix. They react to external stimuli and facilitate the functional adaptation of the proteoglycan and collagen network to mechanical requirements. Via numerous cellular processes they form a complex communicating network which demonstrates coordinated directional reactions. As is common to all tissues in the human body, tendons are subject to age changes which influence the tenocytes, but additionally the structural organization and hence the function of the extracellular matrix. The function and organization of tendons are also affected by mechanical forces, as well as by various cytokines produced in the tissue and by the application of anti-inflammatory medication.
