Journée – surfaces biologiques

Mechanics and Physics of biological surfaces

Many biological surfaces such as cell membranes, cellular cortex or epithelial sheets exhibit interesting multiphysical properties and play a key role in important biological processes such as cell division, tissue morphogenesis or cellular migration. One key property of such systems is that shape deformation is generally created by internal loads which are actively generated within the surface. One typical example is the coupling of chemical processes and the mechanics of active materials involved in morphogenesis. This workshop aims at gathering experimental, theoretical or numerical approaches to better understand the mechanisms underlying the deformation of biological surfaces.

Mécanique et physique des surfaces biologiques

De nombreuses surfaces biologiques telles que la membrane cellulaire, le cortex cellulaire ou les feuillets épithéliaux présentent des propriétés multiphysiques intéressantes et jouent un rôle clé dans plusieurs processus biologiques importants tels que la division cellulaire, la morphogénèse tissulaire ou la migration cellulaire. Une propriété clé de ces systèmes est que la déformation de ces objets est généralement créée par des contraintes internes qui sont activement générées à la surface. Un exemple typique est le couplage des processus chimiques à la mécanique des matériaux actifs impliqués dans la morphogenèse. Ce workshop vise à rassembler des approches expérimentales, théoriques ou numériques pour mieux comprendre les mécanismes sous-jacents à la déformation des surfaces biologiques.
