The main objective of this integrated light microscopic, transmission and scanning electron microscopic study was to describe in greater detail the structural pattern and developmental stages of pulmonary neuroendocrine epithelial cells (PNECs) in the broncho-parabronchial transition (BPT) of both developing and mature quail. In mature quail the BPT appeared as a diaphragm opening into the parabronchial vestibulum. Perpendicular sections revealed two bilayered crest-like entrance folds invested by a uniform population of granular cells with lamellar bodies and a brush border of blunt microvilli. Solitary PNECs were found interlaced between the granular cells on both sides of the BPT. In addition, PNECs with small dense-cored vesicles (DCVs) were found subepithelially in the lamina propria mucosae of the parabronchial compartment of the BPT, which was surrounded by a capsule of granular cells. Furthermore, clusters of PNECs devoid of any epithelial capsule, but with large DCVs were located in the tunica propria mucosae. The first signs of the developing BPT could be identified as early as embryonic day (ED) 13. By ED 17, the area of the future BPT was seen to be invested by a uniform population of granular cells but the entrance fold proper did not appear until after hatching. Solitary or clustered PNECs were demonstrated in parabronchial buds growing into the mesenchyme on ED 12 and 13: either type I PNECs with small DCVs measuring about 80-120 nm or type II PNECs with large dense granules measuring approximately 150-280 nm. Both types of PNECs represented a temporary cell population in the prehatching period. In the parabronchus no PNECs or neuroendocrine epithelial bodies could be demonstrated in mature and immature quail beyond the BPT.

UI MeSH Term Description Entries
D008168 Lung Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood. Lungs
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D008855 Microscopy, Electron, Scanning Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.

D004847 Epithelial Cells Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.
