Intratesticular ducts
Changes in epithelium help to differentiate the intratesticular passages seen in this fetal testis. Stratified germinal epithelium lines the convoluted portion of the seminiferous tubules; simple columnar epithelium (Sertoli cells) lines the straight portions of the seminiferous tubules. Simple cuboidal epithelium lines the rete testis in the mediastinum. 100x
