Single‐nucleus RNA sequencing reveals the distinct heterogeneity of primary pulmonary sarcomas (PPS) and pulmonary sarcomatoid carcinoma (PSC)

Clinical and Translational Medicine, Volume 16, Issue 1, January 2026.
Single‐nucleus RNA sequencing (snRNA‐seq) maps the cellular diversity of pulmonary sarcomatoid carcinoma (PSC) and primary pulmonary sarcomas (PPS). AT2 cells, a major source of epithelial cells in PSC, underwent malignant transformation primarily through epithelial–mesenchymal transition, suggesting AT2 cells may serve as the origin of PSC.
