Epigenetic regulation in mammalian preimplantation embryo development
Preimplantation embryo development involves four stages: fertilization, cell cleavage, morula and blastocyst formation. During these stages, maternal and zygotic epigenetic factors play crucial roles. The gene expression profile is changed dramatically, chromatin is modified and core histone elements undergo significant changes. Each preimplantation embryo stage has its own characteristic epige...
متن کاملInteraction of the Macrophage and Primitive Erythroid Lineages in the Mammalian Embryo
Two distinct forms of erythropoiesis, primitive and definitive, are found in mammals. Definitive erythroid precursors in the bone marrow mature in the physical context of macrophage cells in "erythroblastic islands." In the murine embryo, overlapping waves of primitive hematopoietic progenitors and definitive erythro-myeloid progenitors, each containing macrophage potential, arise in the yolk s...
متن کاملAcetylcholinesterase in mammalian erythroid cells.
The biosynthesis of acetylcholinesterase in mammalian erythroid cells during differentiation and maturation was studied using a cytochemical method. Acetylcholinesterase was actively synthesized in basophilic erythroblasts I and II, and polychromatophilic erythroblasts, where it was present in the nuclear membrane, endoplasmic reticulum and Golgi apparatus. In orthochromatophilic erythroblasts ...
متن کاملManipulation of the mammalian embryo.
Technological advances in manipulation of mammalian embryos outside the maternal environment have resulted in opportunities for study of preimplantation embryo development, identification of developmental phenomena that are unique to mammals, and further improvement of technology. Mammalian embryos may be cultured in vitro at 37 C for up to several days or they may be stored at -196 C indefinit...
متن کاملthe survey of the virtual higher education in iran and the ways of its development and improvement
این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
