Morphogenes, abundantly described during embryogenesis have recently emerged as crucial modulators of cell differentiation processes. Hedgehog signaling, the dysregulation of which causing several pathologies such as congenital defects and cancer, is involved in several cell differentiation processes including adipogenesis. This review presents an overview of the relations between Hedgehog signaling, adipocyte differentiation and fat mass. While the anti-adipogenic role of Hedgehog signaling seems to be established, the effect of Hedgehog inhibition on adipocyte differentiation in vitro remains debated. Finally, Hedgehog potential as a pharmacological target to treat fat mass disorders is discussed.
