L’élongation épithéliale joue un rôle prépondérant au cours du développement. Ce processus morphogénétique peut être décrit schématiquement par trois paramètres : le signal permettant d’orienter l’élongation, la force capable de générer le mouvement et le comportement cellulaire associé. Le follicule ovarien de drosophile, initialement rond s’allonge au cours de son développement résultant en un œuf 2.5 fois plus long que large. J’ai mis en évidence que les follicules traversent au moins trois phases d’élongation successives et je me suis focalisé sur la phase précoce dont les paramètres étaient inconnus. J’ai déterminé que le signal venait d’un groupe de cellules situées aux pôles par la sécrétion du ligand de la voie Jak-Stat puis de l’ac...
