Cilia on cultured ependymal cells examined by scanning electron microscopy

A Scanning and Transmission Electron Microscopic Observation of the Fourth Ventricular Floor in the Mouse

“…of the ventricular surface in the central nervous system by using the scanning electron microscope has been performed by various investigators such as DALEN et al (1971), WEINDEL and JOYNT (1972), ITAKURA (1972, CLEMENTI and MARINI (1972), SCOTT et al (1972), NOACK et al (1972), HOSOYA and FUJITA (1973, HOSOYA and FUSE (1973), CHAMBERLAIN (1973), NAKAMURA et al (1973), COATES (1973a, MESTRES et al (1974) andBRUNI et al (1974). The ultrastructure of the ependyma and its cilia, using a transmission electron microscope, has been studied by TENNYSON and PAPPAS (1962), BRIGHTMAN and PALAY (1963), KOHNO and USUI (1966), TAKEICHI (1966), LEONHARDT and LINDNER (1967), HIRANO and ZIMMERMAN (1967), LEONHARDT (1968), LEONHARDT and PRIEN (1968), NAKAI (1971), MILLHOUSE (1972), SCHINKO et al (1972), NOACK et al (1972, ROHRSCHNEIDER et al (1972), COATES (1973b) andBRUNI et 415 al.…”

Scanning Electron Microscopic Study of the Mitotic Figures in Cultivated Cells

“…FUJITA, TOKUNAGA and INOUE, 1971). On the other hand, very few papers are available which make use of cultivated cells in vitro for scanning electron microscopic study up to the present time (BOYDE, et al, 1968;BOYDE, GRAINGER and JAMES, 1969;FISKIN and MELNYKOVYCH, 1971;DALEN, SCHLAPFER and MAMOON, 1971). The cultivated cells should be very useful material for the observation of the cellular surface of a single cell.…”

“…DALEN et al (1971), the ciliated ependymal cells from the cerebellum of newborn rats. However, no paper has referred to the mitotic figures of these cells.…”

The distribution, activity, and function of the cilia in the frog brain

“…in higher animals, including man, has yet to be evaluated. However, it should be noted that ciliary currents adjacent to the ependyma have been observed in dogs (Konno & Shiotani, 1956); rats (Dalen, Schlapfer & Mamoon, 1971); kittens, monkeys, and man (Hild, 1957); rats and man (Worthington & Cathcart, 1966), and that cilia have been implicated in the flow of c.s.f. along the spinal canal in rabbits and rats (Bradbury & Lathem, 1965).…”
