“…Other tissues as well as the fibrillary plate exhibit orthogonally arranged collagen plies such as the basal lamella of animal epidermis (11) and that of the cornea (12). The scleroblasts, cells that reside as a pseudo-epithelium on the fibrillary plate (10), are fibroblastic in that they appear to synthesize the collagen of the plate and are not separated from the collagen fibrils by a basement membrane (ref.…”

Microtubule staining patterns can be visualized within cells in situ on the surface of fish scales from the squirrel fish, Holocentrus ascensionis, and the common goldfish, Carassius auratus, after incubation with antibodies to sea urchin tubulin and fluorescein-labeled goat antibodies to rabbit immunoglobulin G. Chromatophores in situ from both species reveal a radial microtubule framework that orients the alignment of pigment granules.

“…A high transparency of the dermis therefore seems important for the activity of the pigment cells. Initially, the subepidermal region of the fish skin, characterised by a plywood-like organisation of the collagen fibrils, was called "subepidermal collagenous lamella" (Fujii, 1968) and even renamed "basement lamella" (Nadol et al, 1969). This collagenous stroma constitutes the first deposited matrix of the future dermis, and in order to avoid confusion with the basement membrane, we suggest to use "collagenous dermal stroma " for the larval and early juvenile skin and "stratum compactum" instead of "basement lamella" for the adult skin.…”

“…From the sixties onwards, the introduction of the electron microscope has induced some authors to investigate the structure of fish skin (mainly epidermis), as well as scale structure and development (Sire, 1987). However, apart from one study dealing with skin development (Nadol et al, 1969), all descriptions concerned features of adult skin.…”

“…Each stratum is composed of filaments of one orientation; the orientation of the filaments in the next stratum is at 90 ~ to the first, and so on. The image is reminiscent of the packing of collagen fibers in a fish scale (26) and in the cornea (15). Yet, as is true for the small islands of filaments in the [~ellet of G-actin, the filaments, which measure 55 A in diameter, are readily identifiable regardless of whether they are in transverse, longitudinal, or oblique section.…”

At an early stage in spermiogenesis the acrosomal vacuole and other organdies including ribosomes are located at the basal end of the cell. From here actin must be transported to its future location at the anterior end of the cell. At no stage in the accumulation of actin in the periacrosomal region is the actin sequestered in a membrane-bounded compartment such as a vacuole or vesicle. Since filaments are not present in the periacrosomal region during the accumulation of the actin even though the fixation of these cells is sufficiently good to distinguish actin filaments in thin section, the actin must accumulate in the nonfilamentous state. The membranes in the periacrosomal region, specifically a portion of the nuclear envelope and the basal half of the acrosomal vacuole membrane, become specialized morphologically in advance of the accumulation of actin in this region. My working hypothesis is that the actin in combination with other substances binds to these specialized membranes and to itself and thus can accumulate in the periacrosomal region by being trapped on these specialized membranes. Diffusion would then be sufficient to move these substances to this region. In support of this hypothesis are experiments in which I treated mature sperm with detergents, glycols, and hypotonic media, which solubilize or lift away the plasma membrane. The actin and its associated proteins remain attached to these specialized membranes. Thus actin can be nonrandomly distributed in ceils in a nonfilamentous state presumably by its association with specialized membranes.It is now clear that actin is one of the most common proteins in nonmuscle cells comprising from 10% to 15% of the total protein in cell types such as the amoeba, blood platelets, and cells of the nervous system (see 30 and 38 for references). Unlike those in skeletal muscle, the actin filaments in most nonmuscle cells are transitory, appearing when needed, only to disappear at a later developmental stage. Frequently, these stages are separated by only a minute or two. For example, during cytokinesis filaments now known to be
