Mean-field equations associated with the stochastic system of the VEGF-Delta-Notch signalling pathway for the individual cell system (left column) and the multicellular system (right column).

Here HS(⋅) is the so-called shifted Hill function [78]. Its functional form is given by , where X0, λX,Y and nY are positive parameters (see S1 Text for more details). Description and values of parameters can be found in S1 Table.
