Cortical changes in Acipenserid eggs during fertilization and artificial activation.
I N the complex chain of interrelated processes which make up the early changes in the egg during activation (see Tyler, 1941, 1955; Runnstrdm, 1952; Rothschild, 1956; T. Yamamoto, 1956; Allen, 1958) many phenomena are still unclear : for example, the problem of the fertilization impulse, the rate of its spread, and its relationship with the other changes in the egg; the problem of the origin o...

Mitotic chromosome condensation in the sperm nucleus during post fertilization maturation division in urechis eggs
Changes in the morphology of the sperm nucleus in the egg cytoplasm are mong the immediate events in nucleocytoplasmic interactions during early embryogenesis. Soon after its entrance into the egg cytoplasm, the sperm nucleus of various organisms increases in size with the transformation of condensed chromatin to a diffuse state, resembling the chromatin of an interphase nucleus (2, 13, 15, 16)...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Solubility Changes of Proteins in Sea Urchin Eggs upon Fertilization
The results presented in this paper give evidence of changes in solubility occurring in a protein fraction of the eggs of Arbacia lixula upon fertilization. The electrophoretic analysis indicates that it is only one part of one of the components of the KCl fraction that undergoes the change. However, under some experimental conditions (freezing and thawing of the KCl fraction or extraction of t...
