Involvement of senescent BMAds and the SASP in glucocorticoid-induced bone loss. Glucocorticoid treatment induces primary senescence of BMAds through a positive interacting feedback loop of 15d-PGJ2-PPARγ-INK signaling. The senescent BMAds spread senescence to other bone and bone marrow cells, leading to an accumulation of senescent cells for bone impairment
