We further analyzed ICAM-1 expression in different cell types within the NSCLC tumor microenvironment using a publicly available core NSCLC atlas compiling single-cell RNA sequencing (scRNA-seq) data of 360,038 cells including malignant, epithelial, immune and stromal/endothelial components from 8 studies comprising 159 samples [29] to further explore neoplastic ICAM-1’s weight in NSCLC. Here, ICAM1 is linked to non-small cell lung carcinoma.
