To illuminate the evolutionary trajectory of LUAD from AIS to IAC, high-throughput scRNA-seq and ST data were generated and integrated to create a large-scale, single-cell spatiotemporal atlas of LUAD. We compiled a multi-omics atlas of the early-stage LUAD invasion process that reflects the heterogeneity of cancer cells, the competitive polyclonal origin of LUAD, signalling interactions between cancer cells and the TME, and the pseudo-chronological nature of LUAD invasion. The spatial distribution characteristics of LUAD cells revealed the spatial heterogeneity of LUAD and the mechanism of spatial immune escape in LUAD, which provides strong evidence supporting clinical diagnosis and surgical intervention at the single-cell level. The seurat object of ST data are available on https://drive.google.com/drive/folders/1dkGF4kKMbHSm04DKHg6P_y_iTD1pXCH8?usp=sharing. Overall design: Nine resected samples (TD1-9, three each from AIS, MIA and IAC cases) from nine treatment-naïve patients were collected for droplet-based scRNA-seq. In parallel, six paired samples were subjected to ST Less...
