Figure Lengend Snippet: A producer cell with a diameter of 1 µm was placed in the middle of a very thin rectangular block (1.1 µm thickness) to represent a quasi-two-dimensional system. For the three-dimensional system it was placed in the middle of a cube. For the cube, concentrations at the cube boundaries were set to zero. For the thin plate the concentrations at the four lateral faces were set to zero, and the top and bottom boundaries were insulated (no-flux boundary condition). The total volume of both systems was 1 nL (1·10 6 cells/mL). A time dependent study in COMSOL Multiphysics yielded concentration gradients at several moments. The figure shows the concentrations along the diagonal after 5 hours.
