When decellularizing, the
elastic fibers were diminished, with greater extent in Triton X-100.
VVG is employed for the selective demonstration of
elastic fibers that appear black in the background of the pink collagen fiber content.
Caption: Figure 3: The valve-like structure was composed of fibrillary material with staining properties of fine fibrillary collagen (asterisk) stained with trichrome (a) and methenamine silver impregnation (b), with scattered very fine
elastic fibers stained with orcein (c, d); the anchorage of the valve-like structure was on a thickening of the adjacent endocardium with a coarse compact layer of
elastic fibers (arrow, c, d).
There can also be mucin deposition of varying degrees in the interstitium and decreased
elastic fibers [2].
Emphysematous areas in lung biopsies taken from these patients were distinguished by the characteristic properties of emphysema mentioned above, such as dilated alveoli, the thinning and occlusion of the alveolar epithelium and infiltration of inflammatory cells, the decreases in amount of
elastic fibers, and disorganization of their order.
Similarly, decrease of
elastic fibers in both the outer surface of TA and the subsinusoidal area was significantly higher in both Group 1 and Group 2 (Table 1) (Figs.
The
elastic fibers are fragmented into globules, simulating a pipe cleaner (left).
From these findings, one could speculate that protruding type is a more advanced stage of anetoderma and destruction of
elastic fibers by MMP-2 and MMP-9 could be the main pathogenesis of anetoderma.
In our sample we did not observe
elastic fibers in any of the testes analyzed.
Volume fraction of 8- isoPGF2a and collagen and
elastic fibers in the alveolar septum or airway walls was determined by dividing the number of points hitting the positive tissue by the total number of points hitting alveolar septum or airway walls.
Skin thinning in intrinsic skin aging is reportedly associated with the degeneration of collagen and
elastic fibers. In addition, several studies have supported an intimate relationship between cellular senescence and skin atrophy.

elastic fibers. Crit Rev Biomed Eng 2001;29(3):279-301.
