Abstract
The present invention relates to a process for the production of human epidermal growth factor (hEGF). More precisely, the present invention relates to a process for the mass production of hEGF, comprising in vivo or in vitro multiplication of human cells capable of producing hEGF, and in vitro cultivation of the multiplied human cells to produce hEGF. The hEGF production according to the present invention is much higher than that attained by conventional processes; thus, hEGF can be obtained in a sufficient amount for use in the prevention and treatment of human diseases.
