Abstract

The purpose of this study is to develop transgenic cell line expressing targeted human granulocyte colony stimulating factor (hGCSF) and green fluorescence protein (GFP) genes as well as production of Somatic Cell Nuclear Transfer (SCNT) embryos derived from co-expressed transgenic donor cells. Constructed pPiggy-mWAP-hGCSF-EF1-GFP vector was chemically transfected into bovine fetus cells and then, only GFP expressed cells were selected as donor cells for SCNT. Cleavage and blastocyst rates of parthenogenetic, SCNT embryos using non-TG cell and hGCSF-GFP dual expressed SCNT embryos were examined (cleavage rate: $78.0{\pm}2.8$ vs. $73.1{\pm}3.2$ vs. $70.4{\pm}4.3%$, developmental rate: $27.2{\pm}3.2$ vs. $21.9{\pm}3.1$ vs. $17.0{\pm}2.9%$). Result indicated that cleavage and blastocyst rates of TG embryos were significantly lower (P<0.05) than those of parthenogenetic and non-TG embryos, respectively. In this study, we successfully produced hGCSF-GFP dual expressed SCNT embryos and cryopreserved to produce transgenic cattle for bioreactor system purpose. Further process of our research will transfer of transgenic embryos to recipients and production of hGCSF secreting cattle.
