dc.description.abstractElectroporation is a common method of DNA transfection for many types of eukaryotic cells, but has not been
attempted in avian primordial germ cells (PGCs). DNA uptake in chicken primordial germ cells (PGCs) was tested
using electroporation with and without dimethyl sulfoxide (DMSO). Gonadal tissue and chicken embryonic
fibroblasts (CEFs) were isolated from 6-day-old embryos (stage 29), transfected with pCMVâ carrying the bacterial
lacZ gene, and cultured for 24 h. Gonadal primordial germ cells (gPGCs) were purified from culture using a Ficoll
gradient. The addition of DMSO significantly increased the transfection efficiency of gPGCs but had no effect on
chicken embryonic fibroblasts. Electroporation of gPGCs resulted in an 80% transfection efficiency, compared with
about 17% observed with liposomes. Approximately 200 transfected gPGCs were injected into 2.5-day-old (stage
17) recipient embryos and the eggs were incubated for an additional 3.5 days, 7.5 days or to hatching. The
exogenous gene was detectable in 100%, 67% and 41% of the 6-day-old (stage 29), 10-day-old (stage 36) recipient
embryos and hatched chicks gonads, respectively. PCR analysis of DNA from the hatched chicks showed that
exogenous lacZ DNA was detected only in the gonad and not the liver and heart. These results indicated that
electroporation was a suitable means of transfecting avian gPCGs for the goal of producing transgenic poultry.
