Using the tannic acid-glutaraldehyde fixation it was possible to clearly visualize, with reproducible results, the elastic fiber amorphous material because of its density. The microfibrillar component was also evidenced with a good performance. With this technique the ultrastructural patterns of the oxytalan and elaunin fibers were also demonstrated ...

The Morphogenesis of Elastic Fibers
1977Elastic fibers have been shown to contain two proteins, insoluble elastin and the elastic fiber microfibril, a glycoprotein. The microfibril has been suggested to play a morphogenetic role in determining the presumptive shape and direction of the forming elastic fiber.

Calcification of Medial Elastic Fibers and Aortic Elasticity
Hypertension, 1997Abstract We tested the hypothesis that a simple change in wall composition (medial calcium overload of elastic fibers) can decrease aortic elasticity. Calcium overload was produced by hypervitaminosis D plus nicotine (VDN) in the young rat.

The function of elastic fibers in the arteries: Beyond elasticity
Pathologie Biologie, 2014The main components of elastic fibers, elastin and fibrillin-containing microfibrils play a structural and mechanical role in the arteries and their essential function is to provide elasticity and resilience to the tissues. However, through control of the quiescent contractile phenotype of arterial smooth muscle cells, elastin also acts as an autocrine

Dermal melanocytes and elastic fibers
Journal of Cutaneous Pathology, 1985The relationship between dermal melanocytes and elastic fibers was studied by electron microscopy. In 3 patients with dermal melanoeytosis, the long cytoplasmic processes of the melanocytes were aligned along the long axis of the clastic fiber and encircled or embraced these fibers.

Journal of Cutaneous Pathology, 1996
The capacity of the skin to be stretched and to return to its resting position is correlated to the quantity and to the quality of the elastic fiber network. Although elastic fibers have been demonstrated in scars, the time course of their appearance in scars and their role in scar elasticity has not been elucidated. A study was therefore undertaken to

Stain Technology, 1952
Orcein was first proposed as an elastic fiber stain by Taenzer in 1890, and has proved very useful for the purpose. It is an important constituent of the author's “Quad” stain.

Elastic fiber and cutaneous amyloidoses
Clinics in Dermatology, 1990Abstract The deposition of amyloid in the skin is seen in systemic amyloidosis as well as in primary cutaneous amyloidoses, in which amyloid deposits are seen around the elastic fibers. In this chapter, we will focus on the relationship between amyloid deposits and elastic fibers.

With the development of higher organisms came the need for tissue flexibility and the necessity to withstand stretch. Several unrelated proteins have evolved to satisfy this requirement, including resilin in arthropods, abductin in molluscs, and elastin in the vertebrates (Sage and Gray, 1979).

Elastic fibers in striae distensae
Journal of Cutaneous Pathology, 1988Eight cases with striae distensae associated with obesity or prolonged corticosteroid intake were examined by light and scanning electro microscopy. Fine elastic fibers predominated in early lesions, while thick elastic fibers predominated in older lesions. In early lesions the periphery showed thick and tortuous elastic fibers, but in older lesions it
