Figure Lengend Snippet: Mucus production, barrier integrity and cell viability evaluation for GoC characterization (A) Mucus production in co-culture 9:1 and 7:3 with Alcian blue/Periodic Acid Schiff’s staining. (B) Barrier integrity with LY (20 μg/ml) for co-culture 9:1 and 7:3 day 2, 4, 6, 8; blank - empty chip (Data are represented as mean ± SD. Test: One-way ANOVA t test, p < 0.01 “∗∗”, p < 0.0001 “∗∗∗∗”, n = 4). (C) Barrier integrity with LY (20 μg/ml) for co-culture 9:1 and 7:3 day 2, 4, 6, 8 (Data are represented as mean ± SD. Test: Two-way ANOVA t test, p < 0.05 “∗”, non-significant “ns”, n = 4). (D) Cell viability with CCK-8 cell viability kit for co-culture 9:1, 7:3 and viability control for co-culture 7:3 (0.25% Triton X-100 added in CM in flow for 24 hours at 2 μL/min) (Data are represented as mean ± SD. Test: One-way ANOVA t test, non-significant “ns”, p < 0.0001 “∗∗∗∗”, n = 4). (E) Variance using barrier integrity test with LY (20 μg/ml) for co-culture 7:3 day 2, 4, 6, 8 (Data are represented as mean ± SD. Test: Two-way ANOVA t test, p < 0.05 “∗”, p < 0.0001 “∗∗∗∗”, non-significant “ns”, n = 12–3 independent chips). (F) Variance using cell viability test with CCK-8 cell viability kit for co-culture 7:3 on day 8 in three chips independently No1, No2, No3 (n = 4) and all of them combined No1 + No2 + No3 (n = 12) (Data are represented as mean ± SD. Test: One-way ANOVA t test, non-significant “ns”).
