Thirty-seven rabbit embryos at embryonic days (E) 10-30 were used to study the morphogenesis of the metanephros by light microscope. The primordium of the metanephros appears at E 12 within the pelvic cavity as a spherical ureteric bud capped by metanephrogenic tissue. The nephrogenic spherules and the renal vesicles develop at E 15 while formation of the renal tubules and differentiation of the glomerular capsule take place at E 16. At E 18, differentiation of the glomerular capillaries occurs and the proximal and distal convoluted tubules are clearly first time demarcated. Positive alkaline phosphatase activity and PAS-positive material are confined to the metanephric corpuscles and the luminal border of the proximal convoluted tubules. In addition, the collecting tubules show large masses of intracytoplasmic PASpositive granules. The rabbit metanephros is smooth unipapillary with indistinct renal columns and pyramids. It undergoes migration until reaches its permanent position at E 30 where the right metanephros is located opposite to the level of the 2nd – 4th lumbar vertebrae and the left one is situated opposite to the level of the 3rd – 5th lumbar vertebrae. This migration is accompanied by rotation for about 135 degrees resulting in a dorsomedially located hilus. In conclusion, the stages of development of the rabbit metanephros are similar to those in other mammals but they maintain a delayed sequence.
