Incubation conditions. The incubation conditions used to culture cells are also important. Cell cultures should be incubated in an incubator with a tightly regulated temperature (e.g., a water-jacketed incubator) and CO 2 concentration. Most cell lines grow at 37°C and 5% CO 2 with saturating humidity, but some cell types require incubation at lower temperatures and/or lower CO 2 concentrations.
