Adrenal, testis, and ovary are steroidogenic organs derived from a common primordium that consists of steroidogenic factor 1 (SF1)‐positive precursor cells. SF1 not only defines the steroidogenic lineages in these organs but also controls their differentiation. Recent evidence implicates the Hedgehog (Hh) signaling pathway as a downstream regulator of SF1 in the appearance of steroidogenic cells in these organs. The Hh signaling pathway serves as a common crosstalk component, yet has evolved diverse functions in the expansion and differentiation of the steroidogenic cells in a tissue‐specific manner. The purpose of this review is to compare and contrast the different roles of Hh signaling in these three organs during development. Mol. Reprod. Dev. 77: 489–496, 2010. © 2010 Wiley‐Liss, Inc.
