Lectin Histochemistry Assessment of Seminiferous Epithelium Glycoconjugates in Mouse
Purpose: Plasma membrane glycoconjugates are important determinantsof differentiation and iteraction during spermtogenesis. Which entails miotic and meiosis proliferation, alternation in cell shape and so on. Hihg rates of them synthetized and present in acrosomes. With attention to such importancy, the present study has was designed to analyze glycoconjugates with special terminal sugar residu...
متن کاملLectin Histochemistry of Glycoconjugates in Mandibular Gland of Chicken
The distribution of glycoconjugates in the chicken mandibular gland was studied by means of light microscopic histochemical methods. The staining procedures employed were horseradish peroxidase conjugated lectin, Alcian blue pH 2.5-periodic acid-Schiff (AB pH 2.5-PAS), and high iron diamine-alcian blue pH 2.5 (HID-AB pH 2.5). The lectins used in the present study were Concanavalin A (Con A), Ri...
متن کاملTransfer of Primordial Germ - cells in Xenopus laevis
THERE have been many claims for the segregation of Anuran primordial germcells at an early embryonic stage. Most authors agree that these cells may be distinguished with ease in the most dorsal region of the larval endoderm and, somewhat later in development, at the base of the dorsal mesentery and in the undifferentiated gonad (see review by Johnston, 1951). Bounoure (1934) and Blackler (1958)...
متن کاملLectin-Binding Patterns in the Microenvironment of the Mouse Developing T-Cells
Glycoconjugates and their programmed changes during the course of development in the cell-surface as well as in the extracellular matrix, are known to affect cell differentiation, cellular interaction and other developmental phenomena during embryogenesis. The purpose of this study was to localize N-acetylgalactosamin as well as fucose-containing glycoconjugates in situ during thymus developmen...
متن کاملXpat, a gene expressed specifically in germ plasm and primordial germ cells of Xenopus laevis
cDNAs specific to vegetal poles of Xenopus gastrula embryos were used as a probe to screen a gastrula vegetal pole cDNA library. One of the novel clones isolated had an RNA expression pattern consistent with it being a component of germ plasm and it was thus named Xpat (Xenopus primordial germ cell associated transcript). The open reading frame encodes a 35 kDa protein with no clear homologies....
