Figure Lengend Snippet: a-b , Quantification of HPCS in lineage-traced cells after tracing (n = 4 mice per time point; Mann-Whitney U test). c-d , mScarlet + /EpCAM + (HPCS/all cancer cells, c ) and GFP + /EpCAM + (Traced cells/all cancer cells, d ) at 3 days (3 d) or 14 days (14 d) of lineage tracing (6 to 8 weeks PTI). n = 4 mice per time point. Mann-Whitney U test. e-f , mScarlet + /EpCAM + (HPCS/all cancer cells, e ) and GFP + /EpCAM + (Traced cells/all cancer cells, f ) at 3 days (3 d) or 14 days (14 d) of lineage tracing (12 to 14 week). n = 4 mice per time point. Mann-Whitney U test. g , Cell states in combined tracing experiments from Fig. . scRNA-seq data from HPCS lineage-traced cells are plotted at the indicated timepoints. h , Stacked bar graphs showing the distribution of cell states across individual mice from HPCS tracing experiments shown as stacked bar graphs as in Fig. . Error bars are SEM. i , Distribution of Nkx2-1 , Sftpc , Hopx , and Hmga2 expression from traced LUAD cells at 8 weeks (6 to 8 week tracing, left ) or 14 weeks (12 to 14 week tracing, right ) PTI. j , Percentage of HPCS (red) or other cell states (green) expressing the indicated genes in traced LUAD cells at 8 weeks (6 to 8 week tracing, left ) or 14 weeks (12 to 14 week tracing, right ) PTI. Fisher’s exact test. k , IF images showing co-staining of GFP (green) with either NKX2.1 ( left , red), SPC ( middle , red), or HMGA2 ( right , red). Boxed areas are shown as individual insets below their respective images. Scale bar: 20 µm. l , Percentage of NKX2.1 + ( left ), SPC + ( middle ) or HMGA2 + ( right ) cells in GFP + LUAD cells quantified from IF co-staining of LUAD tissues harvested at 14 weeks PTI after 3 (3 d) and 14 (14 d) days post-tracing. NKX2.1: n = 21 tumours, 3 mice (3 d) and n = 111 tumours, 3 mice (14 d). SPC: n = 59 tumours, 3 mice (3 d) and n = 89 tumours, 3 mice (14 d). HMGA2: n = 84 tumours, 3 mice (3 d) and n = 35 tumours, 3 mice (14 d). Mann-Whitney U test. Error bars are SEM.
Article Snippet: The sections were blocked in donkey immunomix (0.2% BSA (Sigma-Aldrich, 810533), 5% donkey serum (Thermo Fisher Scientific, 31874), 0.3% Triton X-100 (Thermo Fisher Scientific, BP151-100) in PBS (Gibco, 10010-023)) at room temperature for 30 min. Incubation of primary antibodies against GFP (Abcam, ab13970), integrin α2 (Abcam, ab181548), Ki-67 (Thermo Fisher Scientific, 14-5698-82), pan-cytokeratin (Agilent Dako, M351529-2), uPAR (R&D Systems, AF807), Flag (Sigma-Aldrich, F1804), NKX2.1 (Abcam, ab76013), HMGA2 (Cell Signaling, 8179), SPC (Sigma-Aldrich, AB3786), HOPX (Santa Cruz Biotechnology, sc-398703), Cre recombinase (Cell Signaling, 15036) and HNF4α (Cell Signaling, 3113) diluted in donkey immunomix was performed at 4 °C overnight.
