decreased type II pneumocyte number absent type II pneumocytes 2011-02-11T02:42:20Z CL:0002063 FMA:62501 MP:0010812 MPheno.ontology absence of the granular and roughly cuboidal cells typically found at the alveolar-septal junction that modulate the fluid surrounding the alveolar epithelium by secreting and recycling surfactants, and also contribute to tissue repair and can differentiate after injury into a type I pneumocyte; type II cells cover a much smaller surface area than type I cells (less than 5 percent), but are much more numerous and contain lamellar bodies on the apical surface where surfactant is stored absent AT2 absent ATII absent Cuboidal type II cell absent Great alveolar cells absent Lung type 2 cells absent Lung type II cells absent TII absent granular pneumocytes absent type 2 alveolar epithelial cells absent type 2 alveolocytes absent type 2 pneumocyte absent type II alveolar epithelial cells absent type II alveolocytes absent type II cells absent type II pneumonocytes csmith
