We present a model for the migration of glioma cells on substrates of collagen and astrocytes.
The model is based on a cellular automaton where the various dynamical effects are
introduced through adequate evolution rules. Using our model, we investigate the role of
homotype and heterotype gap junction communication and show that it is possible to
reproduce the corresponding experimental migration patterns. In particular, we confirm the
experimental findings that inhibition of homotype gap junctions favours migration while
heterotype inhibition hinders it. Moreover, the effect of heterotype gap junction inhibition
dominates that of homotype inhibition.
