Fig. 3From: Tiotropium/Olodaterol treatment reduces cigarette smoke extract-induced cell death in BEAS-2B bronchial epithelial cellsThe effect of tiotropium/olodaterol on apoptosis and necrosis in BEAS-2B bronchial epithelial cells after CSE exposure. BEAS-2B cells were pretreated with tiotropium/olodaterol for 4 h, followed by treatment with or without 5% CSE for 24 h. The cells were then stained with annexin V-FITC and propidium iodide (PI) and analyzed using flow cytometry. Tio: tiotropium; Olo: OlodaterolBack to article page
