The Fine Structure of Bovine Nasal Cartilage
Bovine nasal cartilage was studied by electron microscopy before and after extraction with 4 M guanidinium chloride or 1.9 M CaCl(2). These solvents removed matrix granules, basophilia, and 85% of the proteoglycan complex, measured as hexuronate. Simultaneously, many collagen fibrils were disaggregated into component microfibrils (approximately 40 A thick). In contrast to the above solvents, ex...
متن کاملThe significance of the fine structure of articular cartilage.
It is a general rule that the fine structure of a connective tissue is closely related to the forces it transmits. This rule, at its simplest, is exemplified in the longitudinal arrangement of tendon fibres, at its most complex in the trabecular structure of bone. Because fibre bundles in a fascia can be seen with the naked eye and because bone trabeculae are visible in a radiograph we are accu...
متن کاملIsolation and characterization of calcifying matrix vesicles from epiphyseal cartilage.
Matrix vesicles, associated with initial calcification in cartilage, have been isolated from bovine fetal epiphyseal cartilage. Cartilage was digested with collagenase, then partitioned into seven fractions by differential centrifugation. The cellular fractions contained over 80% of the DNA in the digest. The extracellular fraction that contained matrix vesicles, in which apatite crystals were ...
متن کاملComprehensive Gene Expression of Rat Epiphyseal Growing Cartilage
Introduction Skeletal growth in long bones depends on the proliferation and subsequent differentiation of chondrocytes in the growth plate. The cellular and molecular events that regulate the highly ordered progression of chondrocytes are under precise spatial and temporal genetic control. We have previously reported the initial characterization of the most abundant genes in this tissue (1). Th...
متن کاملCartilage Resorption in the Tibial Epiphyseal Plate of Growing Rats
An electron microscopic study of the tibial epiphyseal plates of growing rats reveals that the resorption of unmineralized and mineralized cartilage occurs by two different mechanisms. During resorption the unmineralized transverse cartilaginous walls between chondrocytes are invaded by capillary sprouts. At the resorption zone, numerous cytoplasmic processes derived primarily from the perivasc...
