– Centrioles are found in the juxtanuclear cytoplasm of palatal epithelial cells in guinea pigs in all cell layers except the stratum corneum. In the basal and the lower half of the spinous cell layers they are found in the Golgi area. Their fine structure corresponds to that seen in other cell types. Ciliogenesis and single cilia have been observed in basal cells and in cells from the lower half of the spinous cell layer. During ciliogenesis, when centrioles become basal bodies, one end is enveloped by a large vesicle and pericentriolar satellites are present near this end. Besides free cytoplasmic microtubules, pericentriolar microtubules occur emanating from the satellites. Adjacent to basal bodies, cross‐striated structures are often found. The microtubules of a cilium are a direct continuation of microtubules A and B of the basal body. Two central microtubules have not been observed in cilia of squamous epithelial cells. All cilia examined have been located intracellularly. It seems that cells with centrioles have the potentiality to form single cilia even though a special function may not be attributed to them.
