TMPRSS2 and neoplasm: Through inferCNV analysis, we characterized tumor epithelial cells and conducted dimensionality reduction clustering, revealing five distinct cellular subgroups: C0 TMPRSS2+ Tumor Epithelial Progenitor Cells, C1 ANKRD36C+ Tumor Epithelial Progenitor Cells, C2 HK2+ Tumor Epithelial Progenitor Cells, C3 PLP2+ Tumor Epithelial Progenitor Cells, and C4 MKI67+ Tumor Epithelial Progenitor Cells.
