Le système de co-culture 2D est un moyen efficace d’observer comment les deux pièces de diaphonie in vitro, par lequel nous avons montré ici deux différente axée sur la cellule les effets cancérogènes sur les adipocytes de la moelle osseuse.

Les métastases osseuses sont très répandus chez les patients atteints de cancer avancé, mais un traitement curatif n’est pas encore disponible. Au-delà se spécialisant dans le stockage de l’énergie sous forme de graisse, les adipocytes peuvent prendre en charge la croissance tumorale et les métastases dans la moelle osseuse et les autres organes1,2,3,4,5,6. En outre, les adipocytes jouent un rôle essentiel dans la régulation du cancer cell biology7,8,9,10 et métabolisme4,11,12 ,13,14,15,16, tel qu’il est bien comme dans OS métastase1,4,12. Dans le créneau de la moelle osseuse, les adipocytes peuvent aussi affecter le comportement biologique du cancer cellules4,6,17. L’interaction entre les adipocytes de la moelle osseuse et les cellules cancéreuses avec osteotropism est importante pour la compréhension des métastases osseuses. Cependant, on connaît peu.
Se fondant sur les études actuelles, différentes méthodes sont appliquées aux adipocytes, y compris deux ou trois dimensions (2/3D) et ex vivo cultures17,18,19,20,21. Récemment, Herroon et coll. conçu une nouvelle approche de la 3D-culture pour étudier les interactions entre les adipocytes de la moelle osseuse et de cellules de cancer22. Bien que la co-culture 3D est optimale pour imiter physiologique des interactions entre les adipocytes et le cancer cells in vivo, il souffre d’une mauvaise reproductibilité22,23. Par rapport à un système de co-culture 2D, un système de co-culture 3D peut fournir différents phénotypes cellulaires, comme la cellule morphologie21,22,24,25,26. Par ailleurs, la culture ex vivo des fragments de tissus isolés d’os spongieux peut entraîner une excroissance robuste des adipocytes cultivées la moelle osseuse des cellules17.
Contrairement à ces prédécesseurs, cependant, le modèle de culture cellulaire 2D reste une technique classique, fiable et facile pour numérisation rapidement des molécules de candidat et les phénotypes changés en adipocytes ou cancer des cellules in vitro1, 4,6,12,15,27. Pour mieux comprendre la diaphonie entre les adipocytes de la moelle osseuse et des cellules du mélanome, nous fournissons un protocole détaillé pour un système de co-culture 2D des adipocytes de la moelle osseuse avec des cellules de mélanome.

dual effects of melanoma cell-derived factors on bone marrow adipocytes differentiation

La diaphonie entre les adipocytes de la moelle osseuse et les cellules tumorales peut-être jouer un rôle crucial dans le processus de métastase osseuse. Diverses méthodes sont disponibles pour l’étude de la diaphonie significative ; Toutefois, un système bidimensionnel transwell coculture reste un classique, fiable et un moyen facile pour cette étude de diaphonie. Nous présentons ici un protocole détaillé qui montre la coculture des adipocytes de la moelle osseuse et de cellules de mélanome. Néanmoins, un tel système de co-culture pourrait non seulement contribuer à l’étude de transductions signal cellulaire des cellules cancéreuses induites par les adipocytes de la moelle osseuse, mais aussi à l’avenir mécaniste étude de métastase osseuse qui peut révéler de nouvelles cibles thérapeutiques pour OS métastase.

Dans la moelle osseuse, les adipocytes peuvent apparaître dans la tumeur microenvironnement1,13,33,34,35 à un stade précoce pour soutenir la progression de la tumeur par l’intermédiaire de facteurs solubles ou activation de12,6,osteoclastogenesis<sup cl...
