As mentioned above, the surface expression level of EpCAM and TROP2 was generally low in non-tumor tissue; this fact is reflected in tSNE projections colored by their expression and in the vastly increased percentual frequency of the stromal-like cells (CD90+/CD31-/CD45-/EpCAM-) in comparison to epithelial cells (EpCAM+/CD45-/CD31-/CD90-) (supplemental Figs. S3C, D and S4C). Here, PTPRC is linked to neoplasm.
