Abstract
The present invention relates to a process for the production of human erythropoietin. More precisely, the invention relates to a process for the mass production of human erythropoietin, comprising in vivo multiplication of human lymphoblastoid cells capable of producing human erythropoietin, and human erythropoietin production by the multiplied human lymphoblastoid cells. The human erythropoietin production according to the present invention is much higher, in terms of human erythropoietin production per cell, than that attained by conventional processes using in vitro tissue culture; thus, human erythropoietin can be used in a sufficient amount for the prevention and treatment of human diseases.
