“…It has been vigorously denied that ependymal cilia and flagella are motile (Fuchs, 1902, who considered them hygrophoric stereocilia adaptive to the secretory activity of the cells), but Stoklasa (1930) and his witnesses have watched them beating in many animals. fibers, which are usually considered neuroglia and have even been assigned to the category of protoplasmic astrocytes by Marchesani (1926). But as was already known to Babuchin (1863), they are the first elements of the retina to differentiate.…”

“…Information on microglia in the vertebrate retina is more limited. The earliest studies of microglia in the mammalian retina (Lopez-Enriquez, 1926;Marchesani, 1926) date from a few years after the first description of these cells in the nervous system by RioHortega (1919). Since then, several studies have appeared on the morphology and spatial distribution of retinal microglia in mammals (see Table 1).…”

Immunocytochemical techniques were used in conjunction with the QH1 antibody to study the morphological characteristics and distribution of microglia in the avascular retina of an avian species (the quail). The majority of microglial cells appeared in the outer and inner plexiform layers throughout the entire retina, whereas a few microglial cells in the nerve fiber layer were seen only in the central zone of the retina, near the optic nerve head. In the outer plexiform layer, microglial cells were star-shaped, with processes that ramified profusely in the horizontal plane. Fine process tips extended outward radially, insinuating themselves among the photoreceptors. A regular mosaic-like arrangement of microglial cells was evident in the outer plexiform layer, with no overlapping between adjacent cell territories. Microglial cells in the inner plexiform layer ramified through the entire width of this layer, showing radial and horizontal processes. Microglia in the inner plexiform layer also tended to be regularly distributed in a mosaic-like fashion, although there was slight overlapping between adjacent cell territories. Microglia density in this layer was approximately twice that in the outer plexiform layer. This pattern of microglial distribution was similar to that described in vascular retinae of several species of mammals, a finding that suggest that blood vessels are not responsible for the final locations of microglia in the adult retina, and that microglial precursors must migrate through long distances before they reach their precise destination.

“…The mammalian retina contains two types of neuroglial cells (MCtller, 1851;Ramon y Cajal, 1892;Marchesani, 1926;Wolter, 1957;Lessel & Kuwabara, 1963). The major type of glia are the MOiler cells which comprise about 90% of all retinal glia.…”

Distribution of M�ller cells in the turtle retina: an immunocytochemical study

Müller cells are the major type of glial cell in the vertebrate retina, and appear to participate in important structural and metabolic functions. Although the morphological features of Müller cells have been extensively studied, their topographic distribution across the retina has not been previously reported. We have used a Müller cell-specific monoclonal antibody, 19-33, to study the distribution of Müller cells in turtle retina. The antibody was obtained during a search for cell type-specific monoclonal antibodies in the rat retina. Immunoblotting studies show that 19-33 reacts with a 58 KDa protein that is present in Müller cells. Immunocytochemical studies with en face sections of turtle retina show that the density of Müller cells is fairly uniform across the retina although there are small regional differences. We estimate that the mean Müller cell density is about 1600 cells mm-2 of turtle retina and that each turtle retina contains about 54,000 Müller cells.
