Histomorphological study of tubular system and collecting tubules in domestic rabbit's fetuses (Oryctolagus cuniculus)

Abstract

Abstract: The developmental study of tubular system and collecting tubules has been done in the local rabbit's fetuses, which including detection the timing of appearance of metanephros collecting tubules. The study revealed that the differentiation and development of the collecting tubules in metanephros began in the rabbit at 14 day from pregnancy. Also the histological examination showed at the end of pregnant, the tubular system and collecting tubules visible in medulla and less degree in cortex with clear renal pyramids and well developed long sharp pointed papillae. The purpose of our study to provide a more complete quantitive description of the histomorphology of the tubular system and collecting tubules in rabbits during prenatal development.
