Histologically, tendons consist of dense regular connective tissue. The main cellular component of tendons are specialized fibroblasts called tendon cells (tenocytes). Tenocytes synthesize the extracellular matrix of tendons, abundant in densely packed collagen fibers. The collagen fibers are parallel to each other and organized into tendon fascicles. Individual fascicles are bound by the endotendineum, which is a delicate loose connective tissue containing thin collagen fibrils and e… WebIntegra Reinforcement Matrix is an acellular, sterile, porcine dermal matrix intended for the reinforcement of soft tissue where weakness exists and to reinforce soft tissue repaired by suture or suture anchors during tendon repair of the rotator cuff, patellar, Achilles, biceps, quadriceps or other tendons. cryptocitizens nft

The matrix remodeling rate of pathological tendons is increased, which leads to the decrease of mechanical stability of tendons and more vulnerable to injury ( Longo et al., 2024 ). WebTENDON COMPOSITION. The extracellular matrix (ECM) of tendon is composed predominantly of collagen, which accounts for ∼ 60–85% of the dry weight of the tissue. 2 Roughly 95% of the collagen is type I, with small levels of collagen types III, V, XI, XII, and XIV. 3, 4 The collagen forms fiber-like structures at a number of different ... crypto citizenship
