Prostaglandin E2 (PGE2) (a small fat-like molecule made from arachidonic acid).

>Aged muscle stem cells lose EP4 signaling and slip into early commitment or fatal division. PGE2 binding flips chromatin back to an open state, letting the cells live longer and cycle correctly.

>A PGE2 injection gives the treated cells lasting regenerative power. Repeated shots revive resident stem cells, speeding fiber repair and boosting grip force.
