CellMarker Search Cancer Markers

Search the CellMarker 2.0 database for cancer-specific cell markers. Returns marker genes and cell types found in cancer tissue contexts. Use this to identify tumor-specific markers, immune cell markers in the tumor microenvironment, or cancer stem cell markers. Filters results to 'Cancer cell' annotations only. At least one search parameter is required: cancer_type (tissue), gene_symbol, or cell_type.
