Histochemical demonstration of phosphorylase and UDPG-glycogen transferase in fertilized and unfertilized mammalian eggs.
In mammalian eggs, glycogen may well play an important role as an energy source during cleavage. Although the presence of glycogen in rat and rabbit eggs and the fluctuation of its concentration during development have been reported (ISHIDA 1954, 1963), histochemical demonstration of enzymes related to glycogen metabolism has not yet been published. Studies of glycogen metabolism are generally ...
متن کاملHistochemical Studies on Hydrolytic Enzyme Activities
Histochemical observations were carried out on various hydrolytic enzymes in the spontaneous mammary carcinoma of C3H-strain mice. Alkaline phosphatase activity was observed in the luminal border of the tubular structure and in the periluminal surface, which showed a cystic dilatation in ducts and papillae. Capillaries in the stroma showed a high enzymatic activity. Acid phosphatase activity wa...
متن کاملCellular scaffolds in mammalian eggs.
Cellular scaffolds serve as structural components to which various elements of signal transduction pathways can be associated. The association of components on a scaffold can have several important functions, for example they can: 1) associate upstream regulatory components in a cascade that can increase the speed of response to a stimulus; 2) restrict access of substrates to enzymes associated...
متن کاملMolecular causes of aneuploidy in mammalian eggs.
Mammalian oocytes are particularly error prone in segregating their chromosomes during their two meiotic divisions. This results in the creation of an embryo that has inherited the wrong number of chromosomes: it is aneuploid. The incidence of aneuploidy rises significantly with maternal age and so there is much interest in understanding this association and the underlying causes of aneuploidy....
متن کاملHistochemical and ultrastructural studies on experimental gastritis in mice.
Experimental gastritis was produced in BALB/c (? / +) mice by the method of neonatal thymectomy. This atrophic gastritis was confined to the gastric fundobody mucosa and spared antrum. The morphological changes in the gastric mucosa of this type of gastritis have been described in detail during the growth process after thymectomy (1, 2, 3, 6, 10, and 15 months). The mucosa! changes developed fr...
