The present invention relates to a transgenic pig in which an immune rejection response is suppressed during xenotransplantation, wherein a gene coding for heme oxygenase-1 (HO-1) and a gene coding for tumor necrosis factor receptor 1-Fc (TNFR1-Fc) are simultaneously expressed and a gene coding for &#x3b1;-1,3-galactosyltransferase (GGTA1) is knocked out; and a method for producing the same.

Transgenic pig which simultaneously expresses HO-1 gene and TNFR1-Fc gene, and comprises knocked-out GGTA1 gene, and use thereof

The present invention relates to a transgenic pig that expresses sTNFR1-Fc, wherein a gene encoding sTNFR1-Fc, which is a fusion protein of the extracellular domain of human soluble tumor necrosis factor receptor (sTNFR1) and an immunoglobulin Fc region, is introduced; a method for preparing the same; an organ isolated from the transgenic pig; a somatic donor cell line inserted with sTNFR1-Fc gene; a method for preparing a blood sample comprising sTNFR1-Fc; and a method for preparing human sTNFR1-Fc from the blood sample of the transgenic pig. As the transgenic pig can suppress immune response and inflammatory response by secreting an inhibitory substance that suppresses the activity of TNF-&#x3b1; in blood, it can be effectively used for xenograft. Furthermore, since the transgenic pig has a blood type O, it can be transplanted for suppressing inflammatory response, regardless of a blood type of recipient.

Transgenic pig expressing sTNFR1-Fc genes and the uses thereof

The present invention relates to a method for producing a transgenic pig in which immune rejection response is inhibited, and in which human HO-1 genes and TNFR1-Fe fusion genes are simultaneously expressed. The present invention also relates to a transgenic pig for organ transplantation, which is produced by the method, and in which immune rejection response is inhibited. The present invention also relates to a somatic-cell-donating cell strain for producing the transgenic pig, and to a method for producing organs, from the transgenic pig, in which the immune rejection response is inhibited.

Transgenic pig in which HO-1 and TNFR1-Fc are simultaneously expressed, and method for producing same

Provided is a method for producing a cloned dog by enucleating an oocyte of a dog to produce an enucleated oocyte, transferring a somatic cell of the dog into the enucleated oocyte, carrying out electrofusion under optimized conditions to produce a nuclear transfer embryo, and transferring the nuclear transfer embryo into its surrogate mother.
