Electron Microscopy of Solitary Cilia in Human Gingiva and Rat Oral Mucosa

An electron microscopic investigation of human gingiva and rat oral mucosa revealed the presence of solitary cilia primarily in the germinative layer of the epithelium. The cilia were infrequently found in the stromal cells of the lamina propria. These cilia were associated with the diplosome but lacked the central fibrils normally found in motile cilia.
