This cross section of regenerated muscle shows muscle stem cells (red) in their niche along muscle fibers (green). The blue dots are the DNA in the fiber nuclei. Researchers have found that injecting the molecule prostaglandin E2 into muscles after injury induces the division of muscle stem cells and accelerates regeneration. Prostaglandin E2 is an inflammatory molecule released in response to muscle injury or rigorous exercise.
