You treat fibroblasts with cytochalasin, which inhibits microfilaments, or colchicine, which inhibits microtubules, and observe the following: In controls, the cells migrate in a directed way, elongating as they go. With cytochalasin treatment, the cells completely stop migrating while with colchicine treatment, the cells attempt to migrate in several directions at once. The best conclusion for this is: A Cytochalasin prevents cell migration and colchicine prevents directed cell migration. B. Microfilaments are necessary for cell migration and microtubules are necessary for directionality of migration. C. Microfilaments are necessary for cell migration and microtubules are sufficient for…arrow_forwardWhich of the following do not play a role in intracellularmovement?a. microfilaments and intermediate filamentsb. microfilaments and microtubulesc. intermediate filaments and microtubulesd. only intermediate filamentsarrow_forward
