Interactions entre les cellules épithéliales et leur environnement dans les pathologies colorectales
Les cellules épithéliales colorectales interagissent constamment avec leur microenvironnement, et notamment avec les fibroblastes qui représentent la population cellulaire majoritaire au sein du stroma. Que ce soit en condition physiologique ou lors de pathologies comme les maladies inflammatoires chroniques de l’intestin ou le cancer, ces interactions entre l’épithélium et le stroma régulent les phénotypes et les comportements des cellules de ces tissus. Par exemple, les fibroblastes entourant la crypte colorectale, participent activement à la niche des cellules souches colorectales en régulant leur prolifération et les processus de différenciation et migration cellulaire permettant le renouvellement de l’épithélium colorectal. En condition inflammatoire ou tumorale, ces interactions sont altérées ce qui contribue au développement pathologique, y compris le processus métastatique lors d’un cancer.
En combinant des approches morphologiques, fonctionnelles, pharmacologiques et microfluidiques sur des primocultures cellulaires en 3D d’organoïdes colorectaux et de fibroblastes, couplées à des modèles de greffes orthotopiques sur modèles murins, nous étudions les interactions entre les cellules souches colorectales normales ou tumorales, et les fibroblastes, dans les différentes étapes du processus tumoral colorectal.
Interrelationship between epithelial cells and their environment in colorectal diseases
Colorectal epithelial cells constantly interact with their microenvironment, particularly with the fibroblasts which represent the major cell population within the stroma. Under physiological condition or during inflammatory bowel diseases or cancer, these interactions between the epithelium and the stroma regulate the phenotypes and behaviour of the cells in these tissues. For example, fibroblasts surrounding colorectal crypt actively participate to the colorectal stem cell niche by regulating their proliferation, differentiation but also the migration process involved in the renewal of the colorectal epithelium. Under tumoral or inflammatory conditions, these interactions are altered which contributes to the disease development, including the metastasis process in cancer.
By combining morphological, functional, pharmacological and microfluidic approaches to 3D cell primocultures of colorectal organoids and fibroblasts, coupled to orthotopic grafting on murine models, we study the interactions between normal or cancer stem cells and fibroblasts in the various stages of colorectal tumorigenesis.
