Transgenic and genome editing system in mammals and birds. a In mammals, transgenic (TG) and genome edited (GE) offspring can be produced via direct introduction of genome editing tool into the zygote or microinjection of genome edited ESCs into the recipient blastocyst. b In birds, TG and GE offspring can be produced via injection of genome edited PGCs into the blood vessel of recipient
