As a quality check of the enriched population, we assessed that the isolated cells lacked expression of tumor (dsRED), immune (Ptprc) and endothelial markers (Pecam1) and expressed the mouse CAF-specific signature we previously identified (e.g. Rarres2, Fap, Lum, Thy1) (Fig. 3e). The gene discussed is LUM; the disease is neoplasm.
