The female sex hormone estrogen plays an important role in the structural stability of bones. To date, however, it had been unclear exactly which cells were involved in the hormone’s protective function.

Estrogen deficiency leads to uncontrolled expression of RANKL, which can trigger pathological changes in the bones.
