Artificial chondrons in cartilage tissue engineering; A preliminary study;
Introduction Articular cartilage is an important mechanical entity covering the joint surfaces. Damaged cartilage often results in progressive osteoarthritis, because cartilage has a very low self-repairing or self-regenerating capacity [40]. In order to treat osteoarthritis, joint resurfacing, autograft transplants , prosthesis and complete joint replacement have been evaluated [27][47]. Unfor...
متن کاملImportance of Floating Chondrons in Cartilage Tissue Engineering
BACKGROUND Dedifferentiation of chondrocytes remains a major problem for cartilage tissue engineering. Chondrocytes loss differentiated phenotype in in vitro culture that is undesired for repair strategies. The chondrocyte is surrounded by a pericellular matrix (PCM), together forming the chondron. PCM has a positive effect on the maintenance of chondrocyte phenotype during culture in compar...

متن کاملChondrons from articular cartilage: I. Immunolocalization of type VI collagen in the pericellular capsule of isolated canine tibial chondrons.
A heterogenous population of intact chondrons extracted from low-speed homogenates of canine tibial cartilage were stained by indirect immunofluorescence methods with a polyclonal antibody to type VI collagen. In each of the four chondron groups examined, anti-(type VI collagen) anti-serum was concentrated in the capsule immediately adjacent to the chondrocyte complex. A constant but weaker flu...
متن کاملChallenging for cartilage repair
Editorial When we look back on the past 15-year history of cartilage repair, it is clear that remarkable progress has been made in this area. There is no doubt that a lot of studies have been carried out on cartilage repair and chondrocytes since Brittebergs' report on ACI in 1994 [1]. I would like to introduce our multi-pronged approach to cartilage repair. After the 1994 report [1], we perfor...
