Embryo manipulation of the germplasm.
The development of the avian embryo is used to demonstrate the potential for future advances in genomic strategies. A mathematical model is derived to indicate the most useful approaches for using chimeras to access the chicken genome. A review of the way that germ cells are processed through the gonad highlights the need for such an analysis of cell kinetics and indicates that the right rudime...
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 کاملEmbryo Manipulation in Chickens
Chicken embryo manipulation, especially germline manipulation, recently has progressed greatly by devising important experimental techniques, such as embryo culture and primordial germ cell (PGC) manipulation. Embryogenesis and embryonic development in chickens are affected by gravity at various developmental stages. Freshly collected PGC population seems to contain germline-competent PGCs in o...

در این تحقیق به نقش واسطه ای مترجم در ایجاد تغییرات ایدئولوژیک در ترجمه متون سیاسی پرداخته شده است. بدین منظور محقق متنی سیاسی در خصوص ادعاهای آمریکا در مورد برنامه هسته ای ایران را انتخاب کرد. این متن از سایت spacewar.com انتخاب شد که دارای ایدئولوژی مغرضانه در مورد برنامه هسته ای ایران است. سپس یک گروه 30 نفره از دانشجویان کارشناسی ارشدرشته مترجمی زبان انگلیسی دانشگاه شیخ بهایی انتخاب شدند. ا...
15 صفحه اولManipulation of the angiopoietic/hemangiopoietic commitment in the avian embryo.
The hypothesis that the endothelial and hemopoietic lineages have a common ontogenic origin is currently being revived. We have shown previously by means of quail/chick transplantations that two subsets of the mesoderm give rise to endothelial precursors: a dorsal one, the somite, produces pure angioblasts (angiopoietic potential), while a ventral one, the splanchnopleural mesoderm, gives rise ...
