Determination of developmental stages of embryo in the Sea Urchin, Echinometra mathaei
Sea Urchin is one of the most useful tools in developmental biology studies because this organism has the simplest kind of developmental stages. We aimed to determine developmental stages and timetable of Echinometra mathaei embryo (the species of Persian Gulf). The spawning of E. mathaei was induced by 0.5M KCl injection (1ml) into the coelomic cavity. After fertilization, embryos were placed ...

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.
Developmental stages of embryo-like bodies in teratoma testis.
Small bodies, comparable in their morphology with that of the early developmental stages of mammalian embryos, are observed uncommonly in certain testicular teratomata (Melicow, 1940; Dixon and Moore, 1953; Evans, 1956); and although an enormous number of these embryolike structures may be scattered haphazardly throughout a teratomatous growth, it is only rarely that such bodies (Figs. 2, 5) mi...
متن کاملDevelopmental Neurotoxicity of Methamidophos in the Embryo-Larval Stages of Zebrafish
Methamidophos is a representative organophosphate insecticide. The knowledge of its developmental neurotoxicity is limited, especially for zebrafish in the early stages of their life. Four hour post-fertilization (hpf) zebrafish embryos were exposed to several environmentally relevant concentrations of methamidophos (0, 25, and 500 μg/L) for up to 72 hpf. Locomotor behavior was then studied in ...
