On the visceral layer of the mouse tunica vaginalis testis are two populations of mesothelial cells: one carrying numerous surface microvillia and the other with fewer microvilli thus presenting almost bare areas. Intercellular stomata and smaller gaps are seen only between the cells of the bare areas. Underlying the stomata the surface of a second cell, which probably represents the endothelial lining of submesothelial lymph vessels, is often seen. Mesothelial cells of the parietal layer lack microvilli, stomata and gaps but show numerous long filamentous processes on the apical cell surface and at the lateral cell borders where they connect neighbouring cells as they overlie unusually wide intercellular clefts.
一种有许多表面微绒毛，另一种微绒毛较少，因此呈现出几乎光秃的区域。细胞间气孔和较小的间隙仅在光秃区域的细胞之间可见。在气孔下方，常可见到另一个细胞的表面，该细胞可能代表间皮下淋巴管的内皮衬里。壁层间皮细胞缺乏微绒毛、气孔和间隙，但在顶端细胞表面和细胞侧缘有许多长丝状突起，当它们覆盖异常宽的细胞间裂隙时，这些突起连接相邻细胞。
