Figure Lengend Snippet: Embryonic lung fibroblasts stimulate the differentiation of lung progenitors into HT-280 + AEC2 cells. A Top panel: Schematic of the indirect Transwell® co-culture system to determine the effect of irradiated human embryonic lung fibroblasts (ihELF) on the differentiation of D22 NKX2-1 + LPCs into AEC2. Bottom panel: Flow cytometry analysis for CDH1 and HT2-280 of organoids grown in different matrices. Data are expressed as mean ± SEM, n = 4 biological replicates. Dashed lines indicate mean % of HT2-280 positive cells, respectively, after combining the matrix data in both groups. * p < 0.05 by Mann–Whitney U test, no ihELF versus ihELF. B Left panel: Schematic of experimental design to determine the effect of direct versus indirect contact of LPCs with ihELF on the differentiation of D22 NKX2-1 + LPCs to AEC2. Right panel: Flow cytometry analysis for HT2-280 of organoids grown directly versus indirectly with ihELF after 20 days of culture. Data are expressed as mean ± SEM, n ≥ 10 biological replicates
Article Snippet: Human embryonic lung fibroblasts (hELF, 17.5 weeks of gestation, DV Biologics) were cultured in DMEM (Gibco, #11965118) containing 10% (v/v) FBS and 1% (v/v) penicillin/streptomycin.
