Human interferon production with diploid fibroblast cells grown on microcarriers. 1979

D J Giard, and D H Loeb, and W G Thilly, and D I Wang, and D W Levine

A variety of diploid human fibroblast lines have been successfully grown to high densities (greater than 10(6) cell/ml) on recently developed microcarriers. Interferon induction using poly I.poly C and a superinduction procedure resulted in yields greater than 10,000 units/ml with one cell line. A direct comparison of microcarrier cultures to roller bottle cultures showed equivalent interferon yields on a per cell basis and some apparent differences relating to optimum inducer concentrations and kinetics of interferon accumulation.

UI MeSH Term Description Entries
D007372 Interferons Proteins secreted by vertebrate cells in response to a wide variety of inducers. They confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions. Interferon
