ABSTRACT
BACKGROUND:
Primary human lung epithelial cel s are difficult to be isolated and cultured in vitro, which is characterized as limited sources, low cel viability, slow proliferation capacity, and lacking of differentiation capability.OBJECTIVE:
To establish an air-liquid interface model of lung epithelium by in vitro proliferation of human bronchiolar epithelial cel s, which is used for research on function of lung epithelial cel s.METHODS:
Primary human bronchiolar epithelial cel s were isolated using Pronase and DNase I combined digestive methods, and then proliferated using medium containing ROCK kinase inhibitor. The proliferated cel s were used for establishment of the air-liquid interface epithelium model. Cel differentiation was identified using scanning electron microscope, phase contrast microscope and immunofluorescent staining. RESULTS ANDCONCLUSION:
The primary human bronchiolar epithelial cel s could be expanded successful y using medium containing ROCK kinase inhibitor, and the basal cel marker Cytokeratin14 was preferential y expressed in the proliferated cel population, indicating that these basal cel s might be the main subpopulation of human lung epithelial stem cel s. Subsequently, the proliferated cel s under the air-liquid interface could differentiate into ciliated cel s and non-ciliated column cel s. The results suggest that the proliferation and differentiation of human bronchiolar epithelial cel s were maintained in the presence of ROCK kinase inhibitor, and the air-liquid interface could promote the differentiation of human bronchiolar epithelial cel s.
