Abstract/OtherAbstract:
A hollow fiber cartridge may be used in an extraneous recycle loop to facilitate perfusion operation of a stirred tank bioreactor. Retention of cells while removing waste products and replenishment with fresh nutrients allows higher than normal cell densities obtained in batch or continuous culture systems. This system successfully propagated HeLa cells to over 11 million viable cells per milliliter. Much higher perfusion rates (up to 4 vessel volumes per day) were necessary for high density culture of HeLa cells compared to BHK or a hybridoma cell line because of a much higher specific cellular metabolic rate. Cell specific glucose consumption rate, lactate production and ammonia production rates are several times higher for HeLa cells. Reproducible high cell densities and viabilities can be repeatedly obtained after harvest and dilution of a HeLa cell culture by partial drainage and reconstitution in the bioreactor.
