This paper develops a minimal physical model to explain haptotaxis and oscillatory cell migration by linking adhesion strength to protrusive actin activity.

This paper analyzes gene regulatory networks to show how cell fate transitions and spatial pattern formation arise from temporal multistability and network topology.

This study uses a mathematical framework to analyze how stochasticity and nonlinearity influence gene regulatory network motifs, showing how fluctuations affect cell fate decisions.
