Primary culture of respiratory epithelial cells is useful to study the pathophysiology of respiratory diseases. However, such primary culture has been very limited because of its high dependence on the availability of biopsies and the long time required to reach confluence. Therefore, cell lines are an alternative to primary cultures because they reach confluence faster and some can maintain their differentiation abilities. However, unlike primary cultures and native tissues just some cell lines are able to polarize, with normal channel functionality and transepithelial ionic flux.
呼吸道上皮细胞的原代培养对于研究呼吸道疾病的病理生理学很有用。然而,这种原代培养非常有限,因为它高度依赖活检样本的可获得性以及达到汇合所需的较长时间。因此,细胞系是原代培养的一种替代方法,因为它们达到汇合的速度更快,并且一些细胞系能够保持其分化能力。然而,与原代培养和天然组织不同,只有一些细胞系能够极化,并具有正常的通道功能和跨上皮离子通量。
