Gene transfer into older chicken embryos by ex ovo electroporation.
The chicken embryo provides an excellent model system for studying gene function and regulation during embryonic development. In ovo electroporation is a powerful method to over-express exogenous genes or down-regulate endogenous genes in vivo in chicken embryos(1). Different structures such as DNA plasmids encoding genes(2-4), small interfering RNA (siRNA) plasmids(5), small synthetic RNA olig...
متن کاملEx ovo electroporation for gene transfer into older chicken embryos.
In ovo electroporation is an excellent method to ectopically induce or inhibit gene expression in chicken embryos and to study the in vivo function of genes during embryonic development. However, the application of electroporation in ovo to date is limited to an early stage of incubation (< stage 20). In older embryos (> stage 22), the vitelline and allantoic vessels have developed extensively ...
متن کاملBirth of germline chimeras by transfer of chicken embryonic germ (EG) cells into recipient embryos.
This study reports for the first time the production of chicken germline chimeras by transfer of embryonic germ (EG) cells into recipient embryos of different strain. EG cells were established by the subculture of gonadal tissue cells retrieved from stage 28 White Leghorn (WL) embryos with I/I gene. During primary culture (P(0)), gonadal primordial germ cells (gPGCs) in the stromal cells began ...

فرهنگ های گوناگون دریافت ها و تعبیر های مختلفی از تناسب و ادب دارند. بنابراین، ارتباط میان فرهنگی خطرات ذاتی خطای ارتباطی را نشان می دهد. این پژوهش به منظور تعیین وقوع انتقال منظورشناختی زبان در زبان بینابینی زبان آموزان ایرانی، اختلاف منظورشناختی زبان را بین فارسی و انگلیسی در کنش های کلامی پاسخ تحسین و انتقاد بررسی می کند.داده ها از میان 33 آمریکایی انگلیسی زبان، 85 زبان آموز ایرانی در سطوح م...
15 صفحه اولRibosome Crystallization in Chicken Embryos
Isolated tetrameric particles (166S) derived from the crystalline lattices known to appear in hypothermic chicken embryos consist of mature 80S ribosomes which contain all species of ribosomal RNA and a complete set of ribosomal proteins. Ribosome tetramers are not a special type of polysomes since in solutions of high ionic strengths (500 mM KCl and 50 nM triethanolamine-HCl buffer) containing...
