Somatic cell nuclear transfer (SCNT) technique is a key point of producing transgenic animal disease models. During in vitro production of SCNT embryo, the quality of matured oocytes are one of the important factors that regulate embryo developmental capacity. In preliminary test, we confirmed the effect of fibroblast growth factor 10 (FGF10) on porcine oocyte maturation. In this study, we investigated the developmental potential of SCNT embryos treated with the 10 ng/ml FGF10 (10 F) during in vitro maturation of recipient oocytes. The polar body emission rate was significantly higher in the 10 F treated group than control group. After SCNT, although the rate of fusion was no significant difference, the rate of cleavage and blastocyst formation was significantly increased in the 10 F treated group (p < 0.05). In 10 F treated group, the total cell number was increased and the percentage of apoptotic cell was decreased in the blastocyst stage at day 7 (p < 0.1). The transcription level of apoptosis relative gene, Casp3 was significantly decreased, while anti-apoptosis gene BCL2l1 was increased in the 10 F treated group compared to control group. The 10 F treated group was highly expressed the reprogramming related genes, Sox2 and POU5f1. Also, the first cleaving time was more faster and the percentage of cell block was significantly lower in 10 F treated group than in control group. In this study, we confirmed that 10 ng/ml FGF10 has effect on enhance the oocyte maturation and developmental capacity. These results demonstrate that FGF10 treatment can be used for in vitro development of porcine SCNT embryos and subsequent production of transgenic animal model.
