Cancer-associated fibroblasts (CAFs), hematopoietic progenitor cell-like (HPC), cancer cells, and thymic epithelial cells (TECs) were found to express high CD73 levels in HNSCC (Figure 5A), LIHC (Figure 5B), BRCA (Figure S8A), CHOL (Figure S8B) and OV (Figure S8E). Here, NT5E is linked to head and neck squamous cell carcinoma.
