Coordinations of Intracellular Flow, Calcium Signal and Cellular Contraction in Migrating Physarum

Abstract

In this work, we jointly measure the intracellular flow, traction stresses and free intracellular calcium level in physarum microplasmodium during amoeboid locomotion. Our mea- surements relates, for the first time, the intracellular mass transportation, the forces applied on the substrate and the signal of [Ca2+]i with high resolution in both time and space.
