The influence of the mechanical microenvironment on proliferation of progenitor cells in 3D suspension cultures is still poorly understood. We developed a software framework for individual based modeling of three-dimensional cell cultures. The model simulates the proliferation of progenitor cells on microcarriers. The mechanics of the cells are modeled by the Johnson-Kendall-
Roberts potential and the equations of motion of the cells are derived for a friction-dominated system. The cell cycle is broken up into two stages: increase of cell volume and cytokinesis. The microcarriers were simulated with different coating properties and the predicted mechanical stress levels were compared. The simulations show that both compressive and tensile stresses are present and that the stress distribution is strongly influenced by the microcarrier coating properties. These results give an indication that in the future, individual cell-based modeling methods may become a more widely used tool in combination with in vitro experiments in order to optimize cell culture processes.
