Abstract: A process for producing blood coagulation Factor VII in large scale in 3 human cell lines (HepG2, Sk-Hep, and HKB-11) and to select the best recombinant protein producer is described. The murine line BHK-21 was used as control. The data allowed for the assertion that the system used to modify cell lines was efficient, so that all the cells were satisfactorily modified, and produced the protein of interest in a stable form. In addition, when comparing the murine line BHK-21 with the human cells (HepG2, Sk-Hep-1 and HKB-11), the latter proved to be able to produce rFVII more efficiently, which allows us to conclude that human cell lines are a great alternative to produce recombinant blood coagulation factors in large scale.

Abstract: The present invention refers to: 1) the method for the production of recombinant FVIII in human Sk-Hep-1 cells, comprising von Willebrand Factor (vWF) and 2) the population of human cells transduced with a vector encoding the clotting protein (FVIII). The technical object of the present patent application is intended for the cultivation of human cells in suspension and in adhesion and isolation of the culture medium containing the desired protein. The object of the invention is to provide a safer product (free of potential human viruses), that is cheaper and more stable, by means of a method that provides sufficient amounts and on industrial scale to meet the National demand.
