Steroidogenic factor 1/adrenal 4 binding protein (SF-1/Ad4BP) is an essential nuclear receptor for steroidogenesis as well as for adrenal and gonadal gland development. Mesenchymal bone marrow cells (BMCs) contain pluripotent progenitor cells, which differentiate into multiple lineages. In a previous study, we reported that adenovirus-mediated forced expression of SF-1 could transform mouse primary long-term cultured BMCs into steroidogenic cells. For future clinical application, trials using human BMCs would be indispensable. In this study, we examined whether SF-1 could transform human BMCs into steroidogenic cells and compared the steroid profile of these cells with that of mouse steroidogenic BMCs. Primary cultured human BMCs infected with adenovirus containing bovine SF-1 cDNA could produce progesterone, corticosterone, cortisol, dehydroepiandrosterone, testosterone, and estradiol. Such a mixed character of adrenal and gonadal steroid production in human BMCs was supported by the expressions of P450scc, 3β-hydroxysteroid dehydrogenase (3β-HSD), P450c21, P450c11, P450c17, 17β-HSD, and P450arom mRNAs. Unlike mouse steroidogenic BMCs, introduction of SF-1 into human BMCs caused dramatic inductions of both ACTH and LH receptors, thus leading to good responsiveness of the cells to ACTH and LH respectively. Importantly, among several factors that are known to be closely associated with adrenal and/or gonadal development, introduction of only SF-1 enabled the human BMCs to express P450scc and to produce cortisol and testosterone, suggesting that SF-1 is truly a master regulator for the production of steroidogenic cells from human BMCs.
