Scalable lentiviral vector production using stable producer cell lines in perfusion mode
September 17-21, 2017
Lentiviral vectors (LVs) are becoming an important tool in gene and cell therapy and are being utilized in several clinical studies for rare and more frequent genetic and acquired diseases, as well as in cancer therapies. However, two major challenges need to be overcome in order to generate enough material to treat patients: First, current production platforms result in low titers (stable producer cell lines from adherent cell lines) or are not amenable to large scale production (LV produced by transfection). Next, LVs are known to have a low temperature stability. To address these two challenges, the National Research Council Canada has developed packaging cell lines and stable producer cell lines for the production of LVs which can grow in suspension in serum-free media and produce LV in the 106 TU/ml range without optimization. Furthermore, productions are performed in perfusion mode in order to operate at high cell densities and address the low LV stability.
