Which of the following does not occur during muscle fiber maturation?

a. Myoblast cells align through expression of fibronectin and cadherins

b. Myoblast are induced to undergo mitosis by FGF signaling

c. Myotime cells are induced to become myoblast through juxtracrine signaling from the neural tube

d. Myoblasts fuse into myotubes

Expert Solution

The statement - Myotome cells are induced to become myoblast through juxtracrine signaling from the neural tube does not occur during muscle fiber maturation. During muscle fibre maturation, the myotome cells are activated by various proteins such as MyoD and Myf5 which induce its differentiation into the myoblasts. All the other statements occur in the muscle fiber maturation.
