The function of excretion in insects is performed by the Malpighian tubules, a functional equivalent of the vertebrate kidney. Malpighian tubules are long, thin tubes connected to the hindgut. Upon the determination of the Malpighian tubule major cell type early in embryogenesis, the tubular architecture is achieved by extensive cell division and cell rearrangements. During the tube elongation process, cells exchange their neighbors, allowing the short and fat Malpighian tubule primordia to grow and become a thin tube. Cell rearrangement and intercalation underlie the morphogenesis of other epithelial tissues in Drosophila melanogaster, such as the embryonic epidermis. Recent work has provided insights in the cellular and molecular basis of cell intercalation. These advances are reviewed and discussed with regard to what is known about Malpighian tubule morphogenesis. Mature Malpighian tubules are composed of two cell types, each having a specific function in excretion: The principal cells and the stellate cells. Drosophila and mammalian kidney development show striking similarities, as the recruitment of the stellate cells to the Malpighian tubules, like the cells of the metanephric mesenchyme, requires that cells undergo a mesenchymal-to-epithelial transition. The molecular similarities between these two cases is reviewed here.
