Upregulation of cytokines/chemokines by stimulation of respiratory tract epithelial cells*.

*LET cells (1×104 cells per well) were cultured with or without LPS. A sample of culture supernatant (25 µl) was tested using bead-based flow cytometry to compare values (pg/ml). Values exceeding 150 pg/ml are bolded.

将LET细胞（每孔1×10⁴个细胞）于添加或不添加脂多糖（Lipopolysaccharide，LPS）的条件下培养。取25 μl细胞培养上清液样本，采用基于微球的流式细胞术进行检测以对比各组浓度值（单位：pg/ml），浓度超过150 pg/ml的结果将以加粗字体标注。
