title: An autoradiographic study of the renewal of mouse bronchiolar epithelium following bromobenzene exposure.
abstract: This study discusses mice bronchiolar epithelium following bromobenzene (BrBZ) exposure. Our study shows 3 cell types following BrBZ exposure: Clara cells, ciliated cells, and newly discovered BrBZ-resistant nonciliated cells. Through electron microscopic autoradiography, we were able to show the proliferative ability of BrBZ-resistant nonciliated cells. This finding suggests that BrBZ-resistant nonciliated cells may function as progenitor cells. In addition to discovering this new cell type, our results also demonstrate and confirm the proliferative ability of modified Clara cells.
