La méiose ovocytaire comprend une succession de deux divisions cellulaires, sans phase intermédiaire de réplication de l'ADN, permettant l'haploïdisation du gamète femelle en vue de la fusion des génomes parentaux lors de la fécondation. Le caractère fortement asymétrique de ces divisions permet l'expulsion du matériel génétique surnuméraire, dans de petits globules polaires, tout en conservant l'essentiel des ressources cytoplasmiques qui seront nécessaires au développement précoce de l'embryon. De nombreuses études réalisées sur l'ovocyte de souris ont mis en évidence les capacités intrinsèques du gamète à rompre sa symétrie en positionnant son fuseau de manière excentrée à proximité du cortex. En se positionnant de la sorte le fuseau ind...
