NT5E and neoplasm: Analysis of scRNA-seq data confirmed that subsets of myeloid cells express CD73; however, in this dataset, we found that CD73 was much more prominently expressed by tumor cells, with transcripts detected in 35.9% of tumor cells, 1.19 mean-expression (log2(TPM/10 + 1)) than by myeloid cells (2.52%; 0.06 mean-expression), or other cell populations (3.2% of oligodendrocytes, 0% of lymphoid cells) (Fig. 1A–C).
