The use of relaxin improves healing in injured muscle

Abstract:
To improve the functional recovery of injured skeletal muscle, we have focused our efforts on both enhancement of muscle regeneration and prevention of fibrosis. The polypeptide cytokine/growth factor relaxin can inhibit fibrous tissue formation in many tissues. As a member of the insulin-like growth factor family, relaxin also is a potential stimulator of muscle regeneration. In the current experiment, we examined the antifibrotic effect of relaxin in injured skeletal muscle. We also investigated if the injection of relaxin would influence muscle regeneration after injury. Our results demonstrate that relaxin treatment improved histologic and physiologic healing of muscles subjected to traumatic injury.

Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open.
