Fig. 3

Ultrastructural patterns in postoperative specimens of nasal mucosa. a Re-epithelisation with increased cell proliferation (arrowhead) and reorganization of surface specializations (arrows), showing dichotomous branching of microvilli with fibrillary structure, better visible in the inset at higher magnification (white arrow). Scale bar = 2 μm; Inset Scale bar = 0.5 μm. b Columnar pattern of restored epithelial cells. Scale bar = 2 μm. c Extracellular matrix showing normal ratio between amorphic substance and collagen fibers (CF). Scale bar = 2 μm. d Presence of blood vessels containing red blood cells (RBC). Scale bar = 2 μm. e Reorganization of desmosomes (inset) and interdigitated cell junctions. Scale bar = 0.5 μm. f Euchromatic nucleus (Nu) in a metabolically active cell rich in organelles such as rough endoplasmic reticulum (RER) and mitochondria (Mi), diffuse ribosomes and polyribosomes. Scale bar = 0.5 μm
