Using IHC stained for CD73+ cells (Figure 2F), we found that (1) the mean percentage of CD73+ cells were higher in BPC (mean 42.4%) tumors compared to those in GPC (mean 28%), consistent with our transcriptome data (Figure 2G) and (2) %BPC samples with >75% of CD73+ cells was higher than %GPC tumor samples (Figure 2H). The gene discussed is NT5E; the disease is neoplasm.
