Abstract Three methods of isolating primordial germ cells (PGCs) from gonads of 5-day-old chick embryos were compared. PGCs were then cultured in vitro in DMEM/F12 medium containing 10\% fetal calf serum. BrdU incorporation showed that at least 10\% of the PGC population were dividing, under our culture conditions, during the 2nd day of in vitro culture. During this culture period, PGCs were exposed to avian leukosis sarcoma virus-based retroviral vector pseudotyped with subgroup A envelope, carrying the LacZ reporter gene. X-Gal staining showed that PGCs were permissive to infection, with more than 50\% of PGCs expressing the beta-Gal protein. These data represent the first demonstration that PGCs, isolated from gonads of 5-day-old chick embryos, are able to divide in vitro and that it is possible to introduce and express exogenous DNA in chick PGCs maintained in vitro.
