Abstract (en)

[origin: WO2019129891A1] The invention relates to a method for predicting the metabolic condition of a cell culture of cells of a specific cell type. The method comprises providing (102) a metabolic model (402) of a cell of the specific cell type and carrying out the following steps at each of a plurality of points in time during the cultivation of the cell culture: receiving (106) measured concentrations of several extracellular metabolites and a measured cell density in the culture medium; inputting (108) the received measured values as input parameter values into a trained machine learning program logic – MLP (218); predicting (110) extracellular flows (408) of the extracellular metabolites at a future point in time by means of the MLP; carrying out (112) a metabolic flow analysis for calculating the intracellular flows at the future point in time on the basis of the predicted extracellular flows and the stoichiometric equations of the metabolic model.
