TRANSGENIC PIG EXPRESSING HLA-G AND DAF AND THE METHOD OF PRODUCING THEREOF

摘要

A method for producing transgenic pig which expresses HLA-G gene and DAF gene is provided to suppresses immune rejection of natural killer cell(NK cell) and use for cell theraphy and xeno-transplantation. A method for producing transgenic pig clone cell line which expresses human leukocyte antigen-G(HLA-G) gene and decay-accelerating factor(DAF) gene comprises: a step of isolating a somatic cell from HLA-G clonal pig; a step of inducing an expression vector containing DAF gene into the somatic cell; and a step of screening somatic cell in which the expression vector is induced. The expression vector is pCX-EGFP-BSD as a cloning vector. A method for producing the transgenic pig which expresses HLA-G gene and DAF gene comprises: a step of culturing the transgenic pig clone somatic cell line; a step of removing a nucleus of ovum and fusing clone somatic cell; and a step of transplanting the ovum to surrogate mother pig.
