Morphostructural changes of the kidney microvasculature during the prenatal period in Bubalus bubalis

The microcirculation of the foetal kidney was studied in the buffalo using light (LM) and scanning electron microscopy (SEM). The primordial glomerule s originated from the peripheral zone of the metanephros at the stage of 8 cm, CRT. The glomerular capillaries started to differentiate at the stage o f 10-15 cm CRT. They were sparse and showed a few primordial pores. In addi tion, they began to make contacts with primordial podocytes. At the stage o f 40-60 cm CRT, the renal microcirculation showed a complex and almost comp letely organized morphology.
