Interdigitating cells in the lymphoid tissues of bovine fetuses and calves. An electron-microscopic study.

abstract：:The fine structure of boar Leydig cells is re-examined in samples post-fixed with OSO4-K4Fe(CN)6, an elective method to preserve the ultrastructural detail of the endocrine testis. The cells show a pleomorphic arrangement of the smooth endoplasmic reticulum. Large "vesicle-like" dilatations are interspersed in the tub...
