Serial sections of human vaginal and keratinized oral-gingival epithelia were investigated for ciliary structures. Most melanocytes of the gingival epithelium lacked cilia, whereas almost all basal keratinocytes of the deeper portion of the epithelial ridges possessed one cilium each. In the suprabasal layers of the ridges only a few keratinocytes exhibited a single cilium. In the basal layer, at the top of the connective tissue papillae, approximately every second keratinocyte displayed a single cilium. In the suprabasal layers above the ridges no ciliated keratinocytes were observed. The basal cells of the vaginal epithelium were endowed with cilia, while cilia were absent from the suprabasal cells. In the human forearm epidermis most melanocytes and keratinocytes are supplied with a single cilium; it has been suggested that they may play a role in light reception. However, the widespread occurrence of 9 + 0 cilia in epithelial cells of internal epithelia and their coincidence with the sites of renewal of keratinocytes suggests that a relationship may exist between solitary cilia and mitotic activity.
对人阴道和角化口腔牙龈上皮的连续切片进行了纤毛结构研究。牙龈上皮的大多数黑素细胞缺乏纤毛，而上皮嵴深部几乎所有基底角质形成细胞都各有一根纤毛。在上皮嵴的基底上层，只有少数角质形成细胞有一根纤毛。在基底层，在结缔组织乳头顶部，大约每隔一个角质形成细胞就有一根纤毛。在上皮嵴上方的基底上层未观察到有纤毛的角质形成细胞。阴道上皮的基底细胞有纤毛，而上基底细胞没有纤毛。在人前臂表皮中，大多数黑素细胞和角质形成细胞都有一根纤毛；有人认为它们可能在光接收中起作用。然而，9+0纤毛在上皮内上皮细胞中的广泛存在以及它们与角质形成细胞更新部位的巧合表明，单个纤毛与有丝分裂活动之间可能存在关联。
