The implementation of analytical techniques has revolutionized control of cell cultures during bioprocess manufacturing. The parameters used for monitoring cell cultures can be classified into four categories: cellular physiology, cellular environment, cellular metabolites and contaminant monitoring.
Undoubtedly, all these techniques provide us with plenty of information about cell cultures. However, are they enough to understand the behavior of cells in their complex environment?
Example: Cell lines should give consistent productivity and product quality throughout the production process. Many factors such as shear stress may affect cell proliferation and activate genes associated with apoptosis (Bak, Bax, Caspase 3). Hence, the identification of genes expression level will help us to retro control cell culture by adding anti apoptotic proteins.
