Abstract: PURPOSE: A transgenic cloned pig producing human erythropoietin and a method for producing the same transgenic cloned pig are provided, thereby producing a large quantity of human erythropoietin in the urinary bladder of the transgenic cloned pig with reduced costs. CONSTITUTION: The nuclear transfer embryo produced by a fusion of a pig-derived enucleated oocyte with a nucleus of a pig-derived somatic cell transfected and targeted with a gene encoding human erythropoietin is provided. The transgenic cloned pig expresses human erythropoietin in the urinary bladder of pig. The method for producing a transgenic cloned pig producing human erythropoietin comprises the steps of: (a) transfecting and targeting a gene encoding human erythropoietin into a pig-derived somatic cell line to prepare a nuclear donor cell; (b) removing cumulus cells surrounding a recipient oocyte and then the cytoplasm including the first polar body from the oocyte to prepare a pig-derived enucleated recipient oocyte; (c) transferring the transfected nuclear donor cell into the enucleated recipient oocyte and carrying out cell fusion to generate nuclear transfer embryos; and (d) transplanting the nuclear transfer embryo into a surrogate mother pig to produce live offspring.
