Development of transgenic chicken with a gene of human granulocyte colony-stimulating factor using sperm-mediated gene transfer

Transgenic poultry with a gene of human granulocyte colony-stimulating factor (gcsf) was developed by arti- ficial insemination with the transfected sperm using the "Lipofectamin 2000" reagent. The ratio of trans- genic chickens carrying the human gcsf genome was 33.3% of the total number of birds obtained. It was shown that the concentration-of the human G-csfprotein in blood serum oftransgenic specimens varied from 50 to 220 pg/ml. The first generation of poultry was obtained as a result of insemination oftransgenic hens by sperm of anti-transgenic cocks, thereby inheritance of the foreign gene was found in 37.5% of the obtained chickens.
