Abstract

To study the role of insulin-like growth factors (IGF) in podocyte maturation, we isolated and characterized fetal visceral glomerular epithelial cells from human kidneys obtained at 8–18 weeks gestation. Cells were identified as podocyte lineage by their cobblestone morphology and immunoreactivity with synaptopodin, Wilms tumor-1 suppressor gene product (WT-1), complement receptor CR1, and cytoskeletal proteins smooth muscle actin and vimentin. Stimulation of the podocyte cell monolayers with IGF-II resulted in a slight increase in mitogenesis, an effect that was concentration and time dependent and abrogated by co-incubation with exogenous IGF binding protein 2 (IGFBP-2). Western blot analysis of conditioned media revealed that cultured podocytes expressed endogenous IGFBP-2 exclusively. IGF-II stimulation enhanced IGFBP-2 production in a dose- and time-dependent fashion and was associated with an increase in IGFBP-2 mRNA production. These data demonstrate that IGF-II-stimulated IGFBP-2 production appears to inhibit the mitogenic effect of IGF-II, and may have an autocrine effect on the maturation, differentiation, and survival of fetal podocytes.
