Ultrastructural examination of primary and subcultured epithelial cells established in vitro from an abdominal metastasis of a human testicular tumor revealed particles with the morphology of retroviruses. These structures, found only after extensive scanning of the cells, were observed budding from microvilli and from the outer cell membrane and as extracellular particles. Production of these virus particles was stimulated by the incubation of cells in culture medium containing 5-iodo-2'-deoxyuridine and dexamethasone.
对从一名人类睾丸肿瘤腹部转移灶体外建立的原代和传代培养上皮细胞进行超微结构检查，发现了具有逆转录病毒形态的颗粒。这些结构仅在对细胞进行广泛扫描后才发现，观察到它们从微绒毛和细胞外膜出芽，并作为细胞外颗粒存在。在含有5-碘-2'-脱氧尿苷和地塞米松的培养基中培养细胞可刺激这些病毒颗粒的产生。
