Abstrakt: Collagen biosynthesis by organ cultures of the hypertrophic zone of calf growth-plate cartilage was studied. It was found that this tissue devotes a large portion of its biosynthetic commitment towards production of a collagen molecule comprising short collagen chains. This collagen is similar to short-chain collagens synthesized by chick-embryo tibiotarsus, rabbit growth-plate cartilage and chick chondrocytes grown in three-dimensional gels. However, in contrast with the collagen synthesized in these three systems, the short-chain collagen synthesized by calf growth-plate hypertrophic cartilage is stabilized by disulphide bonds localized within the pepsin-resistant triple-helical collagenous domains of these molecules.
