The amniotic plaques in sheep of the Karagouniko breed

Abstract

The structure of amniotic plaques and adjacent epithelium of full term ewes of the Karagouniko breed were studied using scanning electron microscopy (SEM) and light microcopy. The amniotic plaques appeared as cauliflower-like structures mainly trifurcate or as single papillae. The wall of their stems possessed numerous foldings and round openings. Of interest to note was the abundant vascularization observed in sections of the amniotic plaques. The adjacent amniotic epithelium to the plaques revealed a heterogenous surface which was composed of cells of various forms. (C) 2007 Elsevier Ltd. All rights reserved.
