A histochemical demonstration of calcium in the maturation stage enamel organ of rat incisors.
The location of calcium in a rapid-frozen and freeze-substituted maturation stage enamel organ of the rat incisors was demonstrated by means of the glyoxal bis(2-hydroxyanil) (GBHA) staining method, which formed insoluble red precipitates of calcium-GBHA complex. In the ameloblast layer, highly GBHA-reactive tubulo-vesicular structures corresponding to mitochondria and some other membrane-bound...
متن کاملRecapitulation of normal and abnormal BioBreeding rat T cell development in adult thymus organ culture.
Congenitally lymphopenic diabetes-prone (DP) BioBreeding (BB) rats develop spontaneous T cell-dependent autoimmunity. Coisogenic diabetes-resistant (DR) BB rats are not lymphopenic and are free of spontaneous autoimmune disease, but become diabetic in response to depletion of RT6+ T cells. The basis for the predisposition to autoimmunity in BB rats is unknown. Abnormal T cell development in DP-...
متن کاملA histochemical study on lectin binding in the immature enamel and secretory ameloblasts of rat incisors.
Four lectin-fluorescent marker conjugates (Con A-F, MPA-F, PNA-F, WGA-R) were used for visualizing their binding sites on tissue sections by fluorescent microscopy. The immature enamel, Tomes' processes and distal cytoplasm of ameloblasts were stained with MPA-F and WGA-R on paraformaldehyde-fixed and paraffin-embedded tissue sections. The MPA- and WGA-binding glycoconjugates seemed to be main ...
متن کاملEvaluation of Enamel Matrix Derivative (EMD) Teratogenicity on the Rat Embryo Neural Crest Culture
Enamel matrix derivative Emdogain (EMD) is widely used in periodontal treatment in spite of the fact that its effect on the developing embryo has not been elucidated. The aim of this study was to investigate the teratogenic effect of EMD on the rat embryo neural crest cells. The neural crest is a unique population of cells that migrates from the dorsal neural tube along defined pathways and pro...
