We sorted 4 groups of cells: double negative (TdTOSX-;CD45-), representing the non-immune tumor stroma, CD45 single positive (TdTOSX-;CD45+), representing the tumor infiltrating immune populations, TdTOSX single positive (TdTOSX+;CD45-), and double positive (TdTOSX+;CD45+). The gene discussed is PTPRC; the disease is neoplasm.
