title: Human interferon production with diploid fibroblast cells grown on microcarriers.
abstract: 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.
