The current study exploited a combined metabolomics and in silico modeling approach to characterize the cellular mechanisms of Chinese hamster ovary (CHO) fed-batch cultures. The results identified major growth-limiting factors including the oxidative stress and depletion of lipid metabolites. Such key information on growth-related mechanisms derived from the current approach can potentially guide the development of new strategies to enhance CHO culture performance.
