Embryo Manipulation in Chickens
نویسنده
چکیده
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 opposite-sex germline chimeric chickens, but these PGCs probably disappear from the population during in vitro culture. Long-term culture of chicken PGCs makes it possible to transfer foreign DNA into the germline and also contributes to preserving avian genetic resources. Propagation of endangered avian species could become possible via interspecies germline chimeras. Development of techniques producing somatic cell-derived offspring could also be useful to avian germline manipulation.

CRISPR/Cas9 Targets Chicken Embryonic Somatic Cells In Vitro and In Vivo and generates Phenotypic Abnormalities
Chickens are an invaluable model for studying human diseases, physiology and especially development, but have lagged in genetic applications. With the advent of Programmable Engineered Nucleases, genetic manipulation has become efficient, specific and rapid. Here, we show that the CRISPR/Cas9 system can precisely edit the chicken genome. We generated HIRA, TYRP1, DICER, MBD3, EZH2, and 6 other ...

متن کاملControl of blood pressure mediated by baroreflex changes of heart rate in the chicken embryo (Gallus gallus).
Pharmacological manipulation of peripheral resistance via sodium nitroprusside and phenylephrine was used to study baroreflex function over the latter two-thirds of incubation in embryonic chickens. From day 9 to day 19 of incubation, there is a positive linear relation between heart rate and blood pressure, indicating the feedforward action of arterial pressure on heart rate. A reciprocal rela...
