|Description:||The epithelium in this portion of the bronchiole contains many Clara
cells. They are cuboidal cells with round nuclei and pale/white
cytoplasm. The Clara cells have the ultrastructure of secretory cells.
The secretion contributes to the bronchiolar fluid which may help to
reduce surface tension as well. Clara cells are also involved in tissue
repair and regeneration. This is an autopsy specimen and it is not
clear if the depression represents an opening into an alveolus or is an
artifact. PK1588. S1. Original mag. 100 x. H&E. Clara cells.
