Les complexités tissulaires des systèmes multicellulaires confondent l'identification de la relation causale entre les indices extracellulaires et les comportements cellulaires individuels. Ici, nous présentons une méthode pour étudier le lien direct entre les indices contact-dépendants et les axes de division utilisant des blastomeres d'embryon de C. elegans et des perles adhésives de polystyrène.

Complexe de tissus multicellulaires, ce protocole reconstitue la conduite cellulaire d’une manière simplifiée. Une chose est cette technique pour étudier les relations directes entre les protons de conducteur cellulaire et la réponse cellulaire. Ce protocole utilise des perles de polystyrène chimiquement fonctionnelles pour reconstituer les protons du conducteur cellulaire.

Les perles peuvent être coupées avec n’importe quel proton d’intérêt, pour tester leurs effets sur la réponse cellulaire. Nous avons utilisé cette méthode dans C-Elegance sur les embryons de souris. Par conséquent, ce protocole peut être droit aux études des organismes larges.
