Branching morphogenesis independent of mesenchymal–epithelial contact in the developing kidney

Abstract excerpt

Whether mesenchymal-epithelial interactions leading to branching morphogenesis in developing epithelial tissues such as the kidney require direct cell-cell contact or are due to soluble mediators elaborated by the inducing tissue has been the subject of much debate. Here we demonstrate that ureteric bud (UB) epithelium, from which the kidney collecting system and upper urinary tract are derived, can undergo...
