Figure Lengend Snippet: ( A ) RNA sequencing analysis of tumors from various mouse models of lung cancer. The y-axis represents the normalized counts for Tmprss11b . One-way ANOVA with Dunnett’s multiple comparisons test was used for the statistical analysis (RPR2 mice n = 5; RPM mice n = 15; SNL mice n = 4; LP mice n = 6; SL mice n = 9; KP mice n = 8, biological replicates), **** P < 0.0001 (RPR2, RPM, KP), * P = 0.0133 (LP). Plot represents mean ± SD. ( B ) Schematic representation of Ad-Cre mediated tumor induction in SNL mice. Figure created in BioRender. ( C ) Representative MRI images of the mice in ( B ), 3- & 4-months post infection. Red outlines denote tumors (Biological replicates n > 3). ( D ) Representative H&E images of SNL mouse lung, 7 months post infection with Ad-Cre showing distinct regions of LUSC and mucinous LUAD (Biological replicates n > 3). Scale bar, 100 μm. ( E ) H&E image of SNL mouse lung (11 months post infection with Ad-Cre) and RNAscope of Tmprss11b on a serial section. Left, red outline denotes squamous tumors based on H&E staining. Right, yellow outline denotes regions with Tmprss11b expression (red) corresponding to the regions of squamous tumors. The staining was repeated three times with serial sections (technical replicates) and with lung sections from different mice ( n = 4, biological replicates). Scale bar, 2 mm. ( F ) Zoom-in of ( E ) showing Tmprss11b expression by RNAScope in squamous tumors (top panel) and normal lung (bottom panel). Scale bar, 200 μm. ( G ) Representative H&E image with annotations and RNAscope analysis of Tmprss11b (red) and Sox2 (green) in SNL lung sections. Scale bar, 400 μm. .
Article Snippet: We obtained reference single-cell RNA sequencing (scRNA-seq) data from The Tabla Muris Consortium ( Nature 2018) (Schaum et al, ) and spatial transcriptomics (ST) data from relevant datasets.
