PGE2 potentiates the repair of bone and skeletal muscle after injury. PGE2 can not only accelerate the fracture healing process via EP2/4 but also promote the repair of muscles and tendons following injury by EP4. In the process of muscle repair, PGE2 can improve muscle function, regulate muscle-derived stem cells, as well as facilitate muscle formation.
