Histomorphological Development of the Capsule and Stromal Elements in Metanephros of Goat Foetii (Capra hircus)

Abstract

The present study was conducted on the kidneys of 22 goat foetii divided into three groups. In the goat foetus at 45 days of gestation, the mesenchymal cells condensed around the kidney (metanephros). The periphery of the capsule was surrounded by a thin sheet of mesenchymal cells. At 61 days of gestation, the collagen fibres formed a constituent part of the renal capsule. At 120 days of gestation, the renal capsule showed an outer layer composed mainly of collagen and reticular fibres along with smooth muscle cells.
