Alveolar Epithelial Type 1 Cells (AEC-1) are thin, flat, highly elongated cells that line the alveolus and run adjacent to the endothelial cells of the capillaries in the underlying mesenchyme. Together, they form the gas exchange area. AECs are the predominant epithelial cell type in the alv...
In chronic obstructive pulmonary disease, RAS cells are altered transcriptionally, corresponding to abnormal alveolar type 2 cell states, which are associated with smoking exposure in both humans and ferrets. These data identify a distinct progenitor in a region of the human lung that is not found ...

Alveoli Definition, Function & Diagram from Chapter 1 / Lesson 12 543K Discover what alveoli are and learn the meaning through a definition. Explore the alveolar functions by looking at the diagram of the respiratory system. Related to this QuestionWhere...
Organs-on-chips (OOCs) are emerging as predictive tissue modelling tools and as a credible alternative to animal testing. These micro-engineered cell-based systems provide cells with an environment that closely resembles their native in vivo milieu1,2,3. Tissue models of physiologically healthy or...

To solve the question of selecting the incorrect match regarding the type of epithelium and its location, we will analyze each option provided. 1. Understand the Types of Epithelium: - Epithelial tissues are classified based on the number of cell layers and the shape of the cells. - Simple...
Epithelial cells arise from precursors, located at the termini of branching airways, which give rise to alveolar type 2 (AT2) and Clara cells, or eventually alveolar type 1 (AT1) cells. AT2 cells either differentiate into AT1 cells, which form a flattened but expansive barrier mediating the ...
There was an inverse relationship between the degree of alveolar wall thickening and the number of large mononuclear cells of granular type in the alveolar spaces. Corticosteroid treatment suppressed symptoms and signs in a few of the patients whose biopsy specimens showed only slight alveolar wall ...
