From: Quercetin improves epithelial regeneration from airway basal cells of COPD patients
Mucociliary-differentiated cell cultures established from quercetin-treated COPD BC show attenuated levels IL-8 and IL-6. 90% confluent monolayer of COPD BC (obtained from 8 COPD subjects) treated with DMSO (COPD-P) or quercetin (COPD-Q), and normal basal cells (obtained from 8 healthy non-smokers) were cultured at air/liquid interface for 4 weeks. The transwells were transferred to new receiver plates containing fresh medium and incubated for 24 h. Basolateral medium was collected and levels of IL-8 and IL-6 were measured by ELISA. Data represent mean ± SD (n = 8, ANOVA with Tukey post-hoc analysis, *p ≤ 0.05, different from normal; # p ≤ 0.05, different from COPD-P).
