CD47 and head and neck squamous cell carcinoma: Results of these analyses indicated that CD47 was overexpressed in tumors compared to adjacent non-tumor oral tissues and was mostly expressed in HNSCC tissues with ~ 125 transcripts per million (TPM) after the ovarian (OV, ~198 TPM) and lung adenocarcinoma (LUAD, ~195 TPM) (Figure 1A and Supplementary Figure S1).
