the 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.
Movement of the cell surface and change in surface area during cleavage in the newt's egg.
In cleaving eggs of the newt, Cynops pyrrhogaster, the behaviour of the egg surface was analysed by observing linear and area changes in a transplanted piece of cortex which differed in pigmentation from the background. Results from the animal hemisphere showed that the surface in the cleavage plane shrank extensively in the region where the early cleavage furrow was being formed. On both sides...
متن کاملDuring contact activation of plasma, cleavage of surface-bound Hageman
During contact activation of plasma, cleavage of surface-bound Hageman factor (HF) 1 occurs at two closely situated sites, one within a disulfide loop, termed "site 1", and one outside the disulfide loop, termed "site 2" (1). The result of these cleavages is two forms of active HF (2) which we have given the names a-HF a and fi-HFa. Fig. 1 defines these two forms based on their derivation (last...
متن کاملCell surface changes during cleavage of newt eggs: scanning electron microscopic studies.
Scanning electron microscopic studies were carried out on changes of the cell surface during the first cleavage of eggs of the newt, Cynopus (Triturus) pyrrhogaster. A dense population of elongated microvilli, which initially covered a double line indicating the initial furrow and stress marks running on each side of it, became located inside the pigmented area a little apart from its border wi...
