Human sebaceous glands were studied by electron microscopy using lanthanum tracer and freeze-fracture methods. Gap junctions but no tight junctions were found. It is suggested that the essential permeability barrier may be formed by the secreted sebaceous neutral lipid.
利用镧示踪法和冷冻蚀刻法,通过电子显微镜对人类皮脂腺进行了研究。发现了缝隙连接,但未发现紧密连接。提示分泌的皮脂腺中性脂质可能形成了主要的渗透屏障。
