A Simple Go-or-Grow Model of Aerotaxis Along a Self-Generated Gradient

Explore a 47-minute conference talk on a minimal model describing cell colony expansion in response to aerotaxis, presented by Vincent Calvez at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the hypothesis that cells either divide when sufficient oxygen is available or move directionally along oxygen gradients when levels are low. Examine the explicit speed of expansion and the transition between pulled and pushed fronts. Analyze the relative importance of three key parameters: division rate, averaged speed of directional motion, and cell diffusion coefficient. Gain insights into the mathematical methods used to study self-organization in biological sciences, specifically focusing on the behavior of Dictyostelium discoideum colonies.
