..., a different experimental design was applied in that the growth of the condylar process was observed following a provoked periosteal damage. Using 15-day-old rats, the mandibular ramus on the right side was exposed, and the periosteum subjacent to the condylar cartilage was frozen by a cryotechnique. Controls...

...N.A. Ebraheim; H. Yang; J. Lu; A. Biyani; R.A. Yeasting The surface area, thickness and composition of articular cartilage of the atlanto-odontoid joints were investigated in twenty human cadaveric cervical spine specimens. The specimens were also examined grossly and by light microscopy...

Similarly, α-mannosyl residues that had been attached to labelled carrier proteins were strongly bound by the extracellular matrix already during early stages of finger maturation. Staining intensity for heparin gradually increased during chondrogenesis, whereas affinity...

...K. Messner; M. Lundberg; B. Andersson The growing knee joint in immature rats was chosen as a model to study quantitatively bone apposition and thickness of articular cartilage after surgical removal of the medial collateral ligament. In 32 rats, subchondral bone apposition was assessed...

... in those having a raphe, than in tricuspid aortic valves and (2) the location of the cartilaginous foci is significantly associated with the morphology of the aortic valve. The present findings support the hypothesis that, in the Syrian hamster, cartilage forms in the aortic valve as a response to locally...

... in mesenchymal and intermediate cell layers. These features were later manifest deeper in the cartilage as acellular regions and as cell clusters. The changes were similar but more severe when the animals were fed hardened pellets. The thickness of the cartilage was decreased, and chondrocytes appeared small...

...S. Ekman; H. Rodriguez-Martinez; L. Plöen; Åsa Jansson Osteochondrosis is a generalized skeletal disorder that affects the growth cartilage in the growing domestic pig but not in the minipig of wild hog ancestry. In the present study, we compare the ultrastructure of the articular and epiphyseal...

...P. Rother; T.-P. Ranke; F. Forriol; J. Banusch; L. Bauer Changes in the distribution patterns of chondrocytes in the embryonic transitory hyaline cartilage of the tarsus were studied using 56 sagittal section of tarsi from 28 human embryos, with a vertex-foot length from 7.0 to 44.0 cm. The os...
