Morphogenèse du Cœur

Présentation
Le laboratoire Imagine-Institut Pasteur de Morphogenèse du Coeur s'intéresse aux mécanismes embryonnaires de la formation du coeur. Nos recherches fondamentales dans le modèle murin ont des applications potentielles dans le domaine médical, pour les malformations congénitales et la réparation du cœur.
La forme d'un organe est étroitement liée à sa fonction. Pour le coeur, l'architecture du myocarde conditionne la fonction de contraction, et l'alignement des chambres cardiaques la double circulation sanguine.
Sans sculpteur ni ingénieur, comment les cellules s’assemblent-elles pour façonner un organe ? Comment connaissent-elles leurs positions relatives dans un tissu ? Comment leurs comportements sont-ils coordonnés au cours du développement embryonnaire pour générer une forme ?
Nous répondons à ces questions en utilisant des technologies de pointe en génétique, omiques, imagerie 3D, analyse quantitative de données complexes et simulations par ordinateur. Nous travaillons en étroite collaboration avec le Centre de Référence des Malformations Cardiaques Congénitales Complexes (M3C).
D'où vient l'asymétrie du coeur?
