The Cell Junction in a Lamellibranch Gill Ciliated Epithelium
The junctional complex in the gill epithelium of the freshwater mussel (Elliptio complanatus) consists of an intermediary junction followed by a 2-3 micro long septate junction. Homologous and heterologous cell pairs are connected by this junction. After fixation with 1% OsO(4) containing 1% potassium pyroantimonate, electron microscopy of the gill reveals deposits of electron-opaque precipitat...
متن کاملCentriole Morphogenesis in Developing Ciliated Epithelium of the Mouse Oviduct
The differentiating mouse oviduct has been used for the study of centriole morphogenesis because its epithelium is extensively ciliated and centriole formation occurs in a brief period after birth. Proliferative elements, consisting of an extensive fibrillar meshwork encrusted with 75 mmicro granules, were encountered at all ages, but were the only centriole precursors present in younger animal...
متن کاملRecovery of the ciliated epithelium following acute bronchiolitis in infancy.
BACKGROUND Little is known about the longitudinal changes in the ciliated respiratory epithelium of infants following viral bronchiolitis. A study was undertaken to investigate the time required for the ciliated epithelium to return to normal following bronchiolitis in infants treated with inhaled steroids or placebo. METHODS Thirty one previously healthy term infants were studied as part of ...
متن کاملCharacterization of ciliated bronchial epithelium 1, a ciliated cell-associated gene induced during mucociliary differentiation.
Lung epithelial structure is altered in asthma; however, the precise mechanisms underlying epithelial repair, including differentiation from basal to columnar epithelial cells, are not well defined. In the course of random sequencing of a cDNA library from human lung biopsies, we have identified a novel gene, ciliated bronchial epithelium 1 (CBE1). Expression of CBE1 was induced during in vitro...
متن کاملComputational Aspects of Mucus Propulsion by Ciliated Epithelium
This work is focused on the investigation of the mechanical dysfunction and airway clearance efficiency (or lack thereof) of the respiratory system by a quantitative analysis of mucus motion. We perform three-dimensional numerical simulations of the mucus and the ciliated cells present at lung walls (epithelium). In this preliminary work we consider a simplified configuration where the fluid is...
