Enzyme Activities in Chick Embryonic Cartilage
Some characteristic enzymatic activities were determined in chick embryonic cartilage and compared with the analogous activities in bone and liver. Chondrocytes were isolated, broken by sonication, and subjected to subcellular fractionation to yield a nuclear pellet, the mitochondrial, lysosomal, and microsomal fractions, and the high speed supernatant solution. It was established that these fr...
متن کاملThe sulfation of chondroitin sulfate in embryonic chick cartilage epiphyses.
With the use of purified chondroitinase of Proteus vulgaris, a method has been devised for the determination of relative amounts of chondroitin, chondroitin-4-SO*, and chondroitin6-SO4 in cartilage. This method was applied to the analysis of embryonic chick epiphyseal cartilage. With 35S04 and ‘*C-acetate it was possible to study the relationship of embryo age to rate of formation of chondroiti...
متن کاملCartilage turnover in embryonic chick tibial explant cultures.
Growth plate cartilage regulates the rate of growth and ultimate length of several bones in the skeleton. Chondrocytes within the growth plate proliferate, differentiate, enlarge, and die. The extracellular matrix undergoes synthesis, reorganization, and eventually degradation. The majority of research in growth plate physiology has focused on the proliferation and differentiation of chondrocyt...
متن کاملBiosynthesis of procollagens and collagens by tissue explants and matrix-free cells from embryonic chick cornea.
Tendon and cornea of 17-day-old chick embryos primarily synthesize type I collagen as the major collagenous component nd type V collagen as a minor collagenous component. Matrix-free cells isolated from cornea and tendon synthesize and secrete mainly type I procollagen. A short lag period for the secretion of collagenous polypeptides into the medium of cell suspensions is observed. There is no ...
متن کاملThe stabilization of cartilage properties in the cartilage-forming mesenchyme of the embryonic chick limb.
Experiments have been done to determine the time in the development of the embryonic chick limb when the cells in the cartilage-forming area become "stabilized." The particular criterion for stability used in this work was the ability of the cells to resist the infiuences in the limb which cause some limb mesenchyme cells to form cartilage and other limb mesenchyme cells to form soft tissue. Bl...
