... in the formation of mineralized nodules containing matrix vesicles. The nodular surface at day 13 consisted of two or more layers of myofibroblast-like cells, while the deeper zones of the nodule contained cells displaying a morphology typical of calcified hypertrophic chondroblasts. These ultrastructural...

... of mineralization of the intervertebral disks and to determine their suitability as a model for ankylosing spondyloarthropathies. Intervertebral disks taken from affected mice from 4 to 18 weeks of age were studied by electron-microscopic, electron energy-dispersive X-ray microanalysis and selected-area electron...

...K. Satomura; M. Nagayama Rat bone marrow stromal cells were cultured in vitro. At days 14–15 of culture, dense clusters of polygonal cells were formed, and they mineralized 2–3 days later. The cells resembling osteoblasts or young osteocytes were histologically observed to be embedded...

...B. Zimmermann Mineralization at collagen fibrils is regulated by glycosaminoglycans (GAG). Alterations in proteoglycan composition during mineralization as well as inhibition of mineralization by GAGs are well documented. Collagen-GAG interactions during desmoid osteogenesis in fetal rat calvariae...

...H.S. Sandhu; E.A. Tonna Tibiae from 11-day-old chick embryos, injected with 3 H-tetracycline, were autoradiographically analyzed at different stages to localize and study the dynamics of the initial phases of bone mineralization, 3 H-tetracycline was localized within newly formed trabeculae...

..., the fetuses were removed and the radii and ulnae dissected free of soft tissue. The bones were cultured for 6 days in media (BGJ) supplemented with 20% fetal calf serum and 150 µg/ml vitamin C. Growth and mineralization were estimated by measuring the total length of the bone, and diaphysis, and by light...

...Harinder S. Sandhu Actin has been localized inTomes’ processes of the ameloblasts by the immunoperoxidase method using antiserum against purified rat actin. The zone of initial mineralization in dentin also gave a positive reaction. The possibility exists that actin may have a role in local...

...S. Chen; D.R. Eisenmann; A.E. Zaki; S.H. Ashrafi Calcium distribution in secretory ameloblasts was studied in rat incisor enamel in which mineralization was temporarily disturbed by injection of either fluoride or cobalt. Pyroantimonate precipitates of calcium were analysed morphometrically...

... differences in the activities of any of the above enzymes. The results suggest that β-APN-induced inhibition of the bone mineralization may be due to the bone-specific inhibition of alkaline phosphatase and Ca +2 -ATPase. 2 07 1981 30 09 1981 10 7 2008 © 1982 S. Karger AG, Basel 1982...

... of collagen type III support the assumption that the bony labyrinth of the adult guinea pig remains at a low level of development. However, the uniform mineralization, the abundance of osmiophilic lines, and the small amount of the cytoplasm in the osteocytes lead to the conclusion that in the bony labyrinth...

...J. Sela; I.A. Bab Primary mineralization in healing sockets after extraction of molar teeth was studied in rats. The observations obtained by scanning electron microscopy were correlated by transmission electron microscopy. The process is characterized by abundance of extracellular matrix vesicles...

...Michael Silbermann; Gila Maor Immature female mice were treated with daily doses of triamcinolone diacetate. Using histochemical and fluorescent methods, the mineralization pattern of the proximal epiphyseal plate of the humerus was studied at various intervals. Following 1 injection, a noticeable...

... by osteoblasts, derived from mesenchymal cells. Later the fibrillar structure is lost and substituted by a homogenous substance. Chondroid starlike mineral deposits which are composed of needles appear in the vicinity of the cells. The chondral needles are longer and smaller than those in the bone. Finally...
