Specific oxysterols have been shown to be pro-osteogenic and anti-adipogenic. However, the molecular mechanism(s) by which oxysterols inhibit adipogenic differentiation is unknown. We show that the anti-adipogenic effects of osteogenic oxysterol, 20(S)-hydroxycholesterol, are mediated through a hedgehog-dependent mechanism(s) and are
