Morphogénèse: Mécanismes cellulaires régulateurs de l’adhérence et de la migration cellulaire lors de la gastrulation du Xénope

Une propriété fondamentale des cellules animales et humaines est leur capacité d’adhérer les unes aux autres, ce qui leur permet de s’assembler en tissus et organes. La formation de ces structures multicellulaires durant le développement embryonnaire implique des changements très dynamiques de l’adhérence et de la migration cellulaire, qui semblent dépendre du remodelage du cytosquelette d’actine et ses liens avec les molécules d’adhérence. Notre but est de comprendre ces mécanismes de remodelage et leur régulation. Nous étudions aussi des récepteurs de surface dont la fonction est de moduler l’adhérence et la migration en réponse au contact avec les cellules voisines. Pour cela nous appliquons une approche multidisciplinaire combinant imagerie, biologie moléculaire et biochimie, biophysique, différents tests fonctionnels, et modélisation.
