제목 Temperature, a simple but a key environmental parameter that influences cell growth and antibody production the culture of chinese hamster ovary cells
초록 In animal cell culture, temperature is one of the key parameters which influence cell growth and recombinant protein production. Generally, most of mammalian cell cultures are performed at 37℃ which is normal human body temperature.
In this study, to evaluate the effect of temperature on recombinant antibody production, rCHO cells were cultivated at various culture temperatures (33℃, 37℃ and 39℃). When the temperatures were lower than 37℃, cell growth was suppressed, but cell viability maintained at for longer culture periods. When the temperature was lowered from 37℃ to 33℃, the specific productivity was three times higher compared to the control. In contrast, when the temperature was heighten from 37℃ to 39℃, the specific growth rate was increased. Interestingly, when temperature was shifted instantaneously from 37℃ to 4℃ for 5 minutes, significant of increase glucose consumption was observed, which reveals dramatic changes in cellular metabolic activities driven by cold culture environments.
