Abstract

In the cultivation of hybridoma cells HB8178 in suspension, exponential growth was followed by cell death after reaching a maximum cell concentration. We examined the cause of such transition from growth to death. Exogenously added lactate and ammonium did not cause cell death at the concentrations observed at the end of exponential growth. The rate of cell death decreases by diluting the conditioned medium with phosphate buffer saline, suggesting the presence of inhibitory factor(s) in the conditioned medium. This inhibitory factor(s) is dialyzable. Furthermore, the conditioned medium obtained from HB8178 culture also causes transition to death phase for another hybridoma cell line AFP.
