Abstract: | Summary In normal young rats, groups of Clara cells in the bronchioles showed the formation of many cytoplasmic blebs on their cytoplasmic domes. Detached blebs rested on the bronchiolar epithelial cells. The scanning (SEM) and transmision electron microscope (TEM) studies suggest localized changes of Clare cell surface activities by increased formation of cytoplasmic blebs which may represent the apocrine type of secretion.This project was supported by research grants from NIH HD-10139 and the American Heart Association, Kansas Affiliate. We used the Electron Microscope Research Service Laboratory of the University of Kansas Medical Center. |
