Abstract
A method for generating a genome-edited chicken is provided, relating to the technical field of genetic engineering. Ovarian injection in situ is conducted on a hen, where a gene editing reagent is injected into ovarian medulla of the hen that is close to laying eggs, such that the exogenously-injected gene editing reagent can enter developing ovarian follicles through blood circulation. In resulting Go individuals, a chimera chicken with both somatic cells and germ cells edited is successfully and efficiently obtained, with an editing efficiency of the Go individuals reaching up to 36.36%. Compared with a traditional primordial germ cell (PGC)-mediated method, the ovarian injection in situ is time-saving and labor-saving, convenient and rapid, low-cost, and highly safe.
