本文对大鼠大腔卵泡外膜细胞进行了电镜观察。许多类似于成纤维细胞，而另一些则具有平滑肌细胞特有的细胞质丝和致密体。中间结构的含丝细胞似乎代表了前两种类型之间的过渡形式。在小窦卵泡周围也发现了少量平滑肌样细胞，许多黄体具有局部界限清楚的平滑肌被膜。这些观察结果表明，大鼠卵泡外膜中存在可能具有收缩功能的细胞。这些细胞可能在排卵过程中发挥作用。
The cells of the theca externa of large, antral ovarian follicles in the rat were studied by electron microscopy. Many resembled fibroblasts, while others possessed cytoplasmic filaments and dense bodies characteristic of smooth muscle cells. Filament‐containing cells of intermediate structure appeared to represent transitional forms between the two previous types.Small numbers of smooth muscle‐like cells were found also around small antral follicles, and many corpora lutea possessed locally well‐defined coats of smooth muscle.These observations indicate that cells with a probable contractile function are present in the theca externa of ovarian follicles in the rat. These cells may play a role in the process of ovulation.
