Single-cell and spatial transcriptomics reveal a stress-induced EMT-like epithelial subset driving immune activation in silica-injured lung

Abstract excerpt

The mechanism that lung epithelial cells regulate immune responses during chronic injury still remains unclear. Here, we combined single-cell RNA sequencing with spatial transcriptomics to track epithelial dynamics in silica (SiO2)-exposed mouse lungs. By day 56, SiO2 induced significant epithelial proliferation, followed with a distinct C0 subset emerging as the dominant population. C0 cells co-expressed...
