CD274 and neoplasm: After further analysis, C10-Tumor-INHBA and C04-Tumor-CXCL10 had enriched the highest level of cell death signaling (Figure 6C), while the highest expression of CD274 (encoding PD-L1) was in C10 and C00 (Figure 6D), implying a limited correlation between tumor CD274 expression and tumor cell death.
