CSF1 and neoplasm: This process generates synthetic images that resemble multiplex data, in which five categories of cells are distinguished (tumour, stroma, necrotic, vessel, macrophage) and macrophage phenotype is described using the continuous label p. We perform a parameter sweep of the ABM, in which we vary χcm, the strength of macrophage chemotaxis towards CSF-1, and c1/2, the concentration of CSF-1 at which macrophage extravasation is half-maximal, selecting values for χcm and c1/2 from a discrete set of points arranged on a regular grid.
