Abstract: A method for producing transgenic pig capable of expressing colony stimulating factor(CSF) gene in the mammary gland is provided to be able to easily obtain the transgenic pig, which is able to solve the problems of post-translational modification or mass-production and is used as a supplemental agent of treating leukemia and an immuno-potentiating agent, by expressing hGM-CSF in mammary gland. The method comprises the steps of: (a) isolating somatic cell from pig fetus on days 40-80 pregnancy; (b) after preparing an expression vector including a promoter specific to mammary gland such as alphas1-casein, beta-casein, beta-lactoglobulin and whey acidic protein; and a polynucleotide encoding the CSF such as hGM-CSF, introducing it into the somatic cell; (c) after selecting the expression vector-introduced clone somatic cell, culturing it; (d) removing nucleus of ovum collected from sow and fusing it with the clone somatic cell; and (e) transplanting the fused nuclear transfer embryos to surrogate mother pig and delivering piglets.
