the aim of this study is to establish a cell line that directly secrets rFVIIa into cell culture medium: Factor VII and hepsin cDNAs are isolated from HepG2 cell line and cloned into pcDNA3-1 vector. The constructs are co-trasfected to CHO cell line. A cell line that permanently expresses recombinant factor VII (rFVII) and hepsin is established. FVIIa protein is secreted to medium of CHO cells co-transfected with pcNDA3-1-FVII and pcNDA3-1-hepsin. A three- to fourfold decrease in clotting time is observed when human FVII-depleted plasma is used in combination with human thromboplastin in the presence of rFVII, confirming the biological activity of rFVII. A cell line is established expressing FVIIa using genetic engineering methods
