Popis: Mathematical models of living cells have been successively refined with advancementsin experimental techniques. A main concern is striking a balance between modellingpower and the tractability of the associated mathematical analysis. In this work wemodel the dynamics for the transcription factor Hairy and enhancer of split-1 (Hes1),whose expression oscillates during neural development, and which critically enablesstable fate decision in the embryonic brain. We design, parametrise, and analyse adetailed spatial model using ordinary differential equations (ODEs) over a grid cap-turing both transient oscillatory behaviour and fate decision on a population-level. Wealso investigate the relationship between this ODE model and a more realistic grid-based model involving intrinsic noise using mostly directly biologically motivatedparameters. While we focus specifically on Hes1 in neural development, the approachof linking deterministic and stochastic grid-based models shows promise in modellingvarious biological processes taking place in a cell population. In this context, our workstresses the importance of the interpretability of complex computational models intoa framework which is amenable to mathematical analysis.
