Process for the in vitro production of a specific polypeptide in mammalian cells or hybrids thereof, and containing, integrated into their genome, the sequence encoding the specific polypeptide

摘要

The invention relates to a new process for the in vitro production of a specific polypeptide in mammalian cells or hybrids thereof. The process according to the invention is characterised in that the sequence encoding the specific polypeptide is integrated into the genome of the cells, and in that the culture of the cells is carried out in a medium containing one or more substances which induce cellular differentiation.
