These club cells secrete glycosaminoglycans which protect the bronchiolar epithelium.

棒状细胞能分泌糖胺聚糖，来保护细支气管内膜。

Like the club cells, the type II pneumocytes are capable of transforming into type I pneumocyte, so they can also help regenerate and replace damaged cells.

如同棒状细胞，II型肺泡细胞也可以转化成I型肺泡细胞以及替代和修复受损的细胞。

Now the walls of the conducting bronchioles are similarly lined by ciliated columnar cells and mucus secreting goblet cells, as well as a new cell type called club cells.

传导性支气管壁上也有纤毛柱状细胞、分泌粘液的杯状细胞，还有棒状细胞。
