in this review the following steps were singled out from this continuous , strictly controlled organogenesis : determination of the mesoderm during the blastula stage , induction of pronephric nephrons during gastrulation , guided migration of the pronephric duct , mesenchyme-controlled branching of the ureter , induced aggregation of the mesenchymal cells of the metanephric blastema , homotypically controlled polarization of the cells in the renal vesicle and remodelling of the vesicle into the s-shaped body , guided migration of endothelial cells into the nephric blastema and the glomerular crevice , and the matrix interaction ( s ) completing the formation of the glomerular basement membrane with dual origin .
