Several studies demonstrated that IGFs stimulate aromatase activity in ovary but no data on bone are available. In the present study the role of IGF system components on aromatase action has been characterized during osteogenic differentiation in a model of rat tibial osteoblasts. At confluence (day 0) cells have been transferred to differentiating medium supplemented with 1% FCS and delta4androstenedion with or without IGF-II 3 nM, IGFBP-2 1 nM and IGFBP-3 1 nM. Cells have be...
