The ureteric diverticulum grows dorsally into the posterior region of the nephric ridge. Here it enlarges and stimulates the growth of metanephric tubules that come to make up the metanephric kidney. The metanephros becomes the adult kidney of amniotes.[well established][VHOG] UBERON:0005106 VHOG:0001526 uberon metanephric epithelium excretory tube
