WebThe most limited lung epithelial progenitor cell is the alveolar type 2 cell, which divides rapidly to reestablish epithelial continuity in damaged alveoli and then transdifferentiates into alveolar type 1 cells. Less well studied are the mesenchymal progenitor cells that provide vascular and muscular components of the developing lung. WebOct 10, 2016 · Introduction. Pseudomonas aeruginosa, a ubiquitous environmental Gram-negative bacterium, is an opportunistic pathogen of immunocompromised and immunocompetent patients in whom wounds, burns, or foreign objects (i.e., central lines, catheters, and ventilators) disrupt epithelial barriers to infection. Patients with an altered …

"An alveolus consists of an epithelial layer of simple squamous epithelium (very thin, flattened cells), and an extracellular matrix surrounded by capillaries. The epithelial lining is part of the alveolar membrane, also known as the respiratory membrane, that allows the exchange of gases. See more A pulmonary alveolus (plural: alveoli, from Latin alveolus, "little cavity"), also known as an air sac or air space, is one of millions of hollow, distensible cup-shaped cavities in the lungs where pulmonary gas exchange takes place. See more Type I cells Type I cells are the larger of the two cell types; they are thin, flat epithelial lining cells (membranous pneumocytes), that form the structure of the alveoli. They are squamous (giving more surface area to each cell) and have … See more • Blood circulation around alveoli • Diagrammatic view of lung showing magnified inner structures including alveolar sacs at 10) and lobules at 9).
