Ultrastructural aspects of cells with 3 beta-HSDH (delta 5-3 betahydroxysteroid dehydrogenase) activity in female ducks. II. Female Barbary ducks (Cairina moschata)]

The cells making up the thin internal theca of the follicle of the Barbary duck and which contain are 3 beta HSDH enzyme show all of the ultrastructural characteristics of steroid cells: a well-developed smooth reticulum, tubular cristae mitochondria, a considerable load in lipid inclusionologous cells of the Peking duck since they are constantly more dense and their cristae are bigger and less numerous.
