DescriptionThe mesonephros of mammals is a transient renal structure that contributes to various aspects of mammalian fetal development including the male reproductive system, hematopoietic stem cells and vascular endothelial cells. The mesonephros develops from the intermediate mesoderm and forms tubules that are segmented in a similar way to the nephrons of the permanent kidney (but lacking loops of Henle). Early studies have suggested that the mesonephros in marsupials and some placental mammals may perform an excretory function, but these studies have not directly shown active transport of organic anions and cations. Excretory function in the rodent mesonephros has not been investigated. Here, we use live uptake and efflux assays in vitro to show that the murine mesonephros is able to transport organic anions and cations through specific transporters from early in its development. Transcript analysis suggests that there are subtle differences between the transporters involved in uptake and efflux by the murine permanent, metanephric tubules and by the mesonephric tubules. These data suggest that the mammalian mesonephros can provide an excretory function for the early developing embryo, in addition to the excretory function provided by the placenta.
