Under appropriate conditions, the neural stem cells are able to proliferate and to form suspended neurospheres containing stem cells and neuronal and glial progenitors in different stages of differentiation. Our lattice Monte Carlo simulations, taking into account the effect of spatial constraints and cell-cell adhesion on cell diffusion and division, show that i) the neurosphere-size distribution is very broad and ii) the spatial distribution of various cells inside neurospheres is heterogeneous.
