Derailing heterotopic ossification and RARing to go

Retinoic acid receptors inhibit chondrogenesis, but their ability to block the cartilaginous scaffold of heterotopic endochondral ossification has not been explored. A study in mice shows that agonists of retinoic acid receptor-γ potently inhibit heterotopic endochondral ossification, suggesting therapeutic potential in people with this condition (pages 454–460).
