Abstract
The present invention relates to a process for the production of human Multiplication-Stimulating Activity (hMSA). More precisely, the invention relates to a process for the mass production of low-cost hMSA, comprising in vivo multiplication of human cells capable of producing said substance, and subsequent in vitro production of hMSA with the multiplied human cells. hMSA production according to the present invention is much higher, about 2-50-fold higher in terms of hMSA production per cell, than that attained by conventional processes: thus, hMSA can be used in a sufficient amount in the prevention and treatment of human diseases.
