Abstract: In this study, in order to provide a nuclear for somatic cell nuclear transfer and production of transgenic animals, cationic liposome-mediated transfection of homologous recombination FGF5 gene knockout vector to somatic cell. After positive and negative selection obtained 51 cell clones, which remaining 12 clones after propagation, and ultimately get 4 positive cell clones by the molecular indentification of DNA and RNA levels, namely established the FGF5-knockouted Inner Mongolia Arbas cashmere goat fetal skin fibroblast cell line. Compared with normal somatic cell, the four FGF5 -knockouted positive cell clones had occurred very significant changes in cell morphology, traits and growth characteristics: bigger cell volume;fuzzy boundaries, reduced stereoscopic;growth rate dramatic decline;trypsin digestion time required was significantly increased. This study showed that these changes might be due to FGF5 gene knockout, cell transfection, drug selection and other roles.
