This study uncovered the heterogeneity of tumor cells of human glioblastoma, however these tumor samples were depleted of tumor-infiltrated leukocytes (CD45+) prior scRNAseq and then the downstream analyses were only focused on cancer cells [420 cells with cancer-related copy number variations (CNVs)] thus a bigger picture of tumor heterogeneity beyond cancer cells could not be established. This evidence concerns the gene PTPRC and cancer.
