Modeling and simulation can be a powerful tool for bioprocess design and cell culture process development. We now present InSiliCHO, an open source tool for in silico simulation of Chinese hamster ovary (CHO) cell dynamics. InSiliCHO provides a robust foundation for advancements in process development cell culture, cell culture simulation, and more.
You can try InSiliCHO online in our app, or download the Python package with pip.
Simulation tools like InSiliCHO empower researchers to:
For example, InSiliCHO models demonstrate greater detail and accuracy in describing the relationship between initial glucose concentrations, process temperature, and cell density over 150 hours compared to standard Design of Experiments (DoE) techniques.
See here for a comparison of process dynamics as described by a typical response surface as obtained with DoE (top), versus a response surface from a process model (bottom).

InSiliCHO is based on the model described in Möller et al., 2020 [1], which captures critical parameters, such as:
The dynamics of the model are based on known characteristics of CHO, and the default parameters used in the model were chosen to reconstruct experimental data with good fidelity, proving it as an invaluable tool for cell line development and process optimization.
