Little is known about ciliogenesis as it proceeds through the entire airway tree, from the trachea to the terminal bronchioles, especially during the postnatal period. The purpose of this study was to define the spatial and temporal (prenatal and postnatal) pattern of normal cilia development in the mouse. Three airway generations representing the entire airway tree were examined: trachea, loba...

We investigated the oligosaccharide sequence of glycoconjugates, mainly sialoglycoconjugates, in the horse oviductal ampulla during oestrus by means of lectin and pre-lectin methods such as the KOH-neuraminidase procedure to remove sialic acid residues and incubation with N-glycosidase F to cleave N-linked glycans. Ciliated cells displayed N-linked oligosaccharides throughout the cytoplasm. The...

BACKGROUND Ciliated cells play a central role in cleansing the airways of inhaled contaminants. They are derived from basal cells that include the airway stem/progenitor cells. In animal models, the transcription factor FOXJ1 has been shown to induce differentiation to the ciliated cell lineage, and the RFX transcription factor-family has been shown to be necessary for, but not sufficient to in...

The olfaction in fish is generally related with water ventilation process. This study emphasized on the surface structures of the olfactory neuroepithelium and cytological details of the ciliated epithelial elements (i.e., ciliated sensory receptor cells and ciliated supporting cells) in relation to olfaction during water ventilation in a mudskipper, Pseudapocryptes lanceolatus; a teleostean: g...

Topographic and ultrastructural changes in the infundibular segment of goat (Capra hircus) oviduct has been studied during the follicular and luteal phases of the oestrous cycle. Histologically, the mucosal epithelium of the infundibulum revealed characteristic pattern of changes in the number, height, branching of the mucosal folds and relative frequency of ciliated and secretary cells during ...

I . Application of the Gomori method to sections of the terrestrial nemertine Geonemertes dendyi shows that there is no alkaline phosphatase in the flame cells or in the distal glandular canal of the protonephridia. But the proximal ciliated convoluted canal and the branching ciliated terminal ducts are rich in this enzyme. 2. Sections of the terrestrial triclad Rhynchodemus terrestris show the...

Bacteria of the genus Bordetella adhere preferentially to ciliated respiratory epithelial cells. We investigated the specificity of this unique tropism by assessing the concentration-dependent adherence of the three Bordetella species to ciliated cells from different hosts. Bordetella pertussis and Bordetella parapertussis adhere better to human ciliated cells than to those from rabbits, mice, ...

The skin of Xenopus embryos contains a population of specialized ciliated cells that are distributed in an evenly spaced pattern. Here we describe two successive steps that govern the differentiation and the generation of the spacing pattern of these ciliated cells. The first step occurs in the inner or sensorial layer of the non-neural ectoderm where a subset of cells are chosen to differentia...

Sir, Cases of cutaneous cysts lined by ciliated epithelium have rarely been documented, and only a few cases of such cysts in the vulvar vestibulae have been reported (1–3). The origin of the cysts is controversial because the location is so anatomically specific. In this report, we describe a 14-year-old girl with a ciliated cyst of the vulva (CCV), the lining cells of which were positive for ...
