“…Fine collagen fibrils with a banding pattern are formed at an early stage of collagen fibril formation in vivo, developmentally, or during the initial stage of wound healing (Rizk 1980;Craig and Parry 1981). During wound healing, the fibrils are stained with anti-type V collagen antibody, but type I collagen is rarely found in the fibrils (Betz 1995).…”

Reconstituted type V collagen fibrils as cementing materials in the formation of cell clumps in culture

Previous studies have reported that type V collagen is an anti-adhesive substrate for cultured cells in that the cells detach from culture dishes coated with type V collagen molecules or polypeptides derived from them. We have noticed that human fetal lung fibroblasts (TIG-1) initially show no reduction in adherence to and spreading on a dish coated with reconstituted type V collagen fibrils but eventually detach from the dish and form cell clumps. To determine the way in which reconstituted type V collagen fibrils are involved in cell clump formation, we have followed the fate of the fluorescence of type V collagen fibrils pre-labeled with fluorescein isothiocyanate. Essentially, all the fluorescence disappeared from the dish surface as the cells detached and was condensed in the cell clumps. The cells that were recovered from clumps and dissociated into separate cells by trypsin treatment proliferated normally after they were seeded on a bare culture dish. This result and those from gel electrophoresis, fluorescence microscopy, and a cell proliferation assay indicate that the cell detachment from the dish is not caused by cell necrosis or apoptosis but by cellular motility together with the unique features of type V collagen fibrils. Not only the adherence of type V collagen fibrils to TIG-1 cells is much stronger than that to the culture dish, but the fibrils are retained on the cellular surface. The strong adherence of type V collagen fibrils to cells plays a role in cementing TIG-1 cells together.

“…The dif ference of properties suggests that human masseter muscles contribute to a large part to the function of jaw movements with other masticatory muscles. Rizk [9] reported that a delicate reticulum network of very fine fibers filled the space of large parallel collagen bundles of the aponeurosis in the ventral abdominal wall of the rat. In our results, these irregular collagen fibers were not found among the colla gen bundles, but a few elastic fibers were found in the superficial and middle portions of tendon in masseter mus cles at an ultrastructure level.…”

In the masticatory muscles, the development of bundles of the tendon was examined: they were composed of many collagen fibers and a few elastic fibers. In the masseter muscle, the property of the tendon differs in the distribution and size of collagen fibers and elastic fibers in comparison with those of other masticatory muscles. This difference is concerned with the kinetic force for the stress or the stretch of each tendon and muscle during jaw movement.

“…In general, collagenous fibrils of connective tissues can be classified into two types: large, straight parallel fibrils (Fawcett, 1986); and helically arranged, wavy fibrils that form sinuous bundles or threedimensional sheaths (Rizk, 1980). The connective tissues are composed of type I, type III, and type V which indicate intermixed fibrils by chemical and immunohistochemical methods (Light and Champion, 1984;Mayne and Sanderson, 1985).…”

The morphology of the sternocleidomastoid muscle (SCM) of human fetuses, ranged from 12 to 32 weeks gestation, was investigated by a light microscopy and a scanning electron microscopy. The collagenous fibers of the perimysium of the SCM formed complex structures from 24 weeks gestation by contrast to fibers of the endomysium of the SCM. The cross-sectional area (CSA) of the bundle of muscle fibers and the CSA of the individual muscle fibers of the SCM increased during development from 12 to 32 weeks gestation, in a process linked to the development of the perimysium. Therefore the perimysium affects and controls to the muscle fiber of the developed SCM and acts to resisting stretch forces in the movements. The changes in the arrangement and development of the collagenous fibers in the perimysium may be correlated to with these of the muscle fibers.
