Elastic fibres.
Elastic fibres are essential extracellular matrix macromolecules comprising an elastin core surrounded by a mantle of fibrillin-rich microfibrils. They endow connective tissues such as blood vessels, lungs and skin with the critical properties of elasticity and resilience. The biology of elastic fibres is complex because they have multiple components, a tightly regulated developmental depositio...
متن کاملAbnormal deposition of collagen/elastic vascular fibres and prognostic significance in idiopathic interstitial pneumonias.
BACKGROUND Vascular remodelling has recently been shown to be a promising pathogenetic indicator in idiopathic interstitial pneumonias (IIPs). AIM To validate the importance of the collagen/elastic system in vascular remodelling and to study the relationships between the collagen/elastic system, survival and the major histological patterns of IIPs. METHODS Collagen/elastic system fibres wer...
متن کاملTwo techniques for electron opaque staining of elastic fibres using tannic acid in fresh and formalin fixed tissue.
Two electron microscopic staining techniques, one using tannic acid-glutaraldehyde as a fixative, and the other using tannic acid-uranyl acetate solution as a stain on ultra-thin sections of glutaraldehyde fixed material, were directly compared for elastic fibre staining on several human and animal tissues. Various concentrations of tannic acid were compared using both techniques. The two techn...
متن کاملBer-H2 (CD30) Immunohistochemical Staining of Human Fetal Tissues
OBJECTIVE CD30 antigen has long been considered to be restricted to the tumour cells of Hodgkin's disease and of anaplastic large cell lymphoma as well as to T and B activated lymphocytes. It is now apparent that the range of normal and neoplastic cells, which may express CD30 antigen, is much wider than was at first thought. In order to gain insight into the physiological function of CD30 anti...
متن کاملVital Staining of Connective Tissues
When trypan blue is injected intravenously, the animal appears blue within a few minutes, not only in its integument, but in the internal organs as well. 12 or more hours after the administration of the dye, there are innumerable granules within macrophages and other colloidopexic cells, easily demonstrable by ordinary histological technique. But the animal is blue long before such granules are...
