All the ESCC samples and non-neoplastic samples were fixed with 10% neutral buffered formalin, embedded in paraffin, and then sectioned. Then immunohistochemistry was carried out. Figure 1A: HAX-1 staining is strong positive in ESCC samples (400×); Figure 1B: HAX-1 staining is weakly positive in ESCC samples (400×); Figure 1C: HAX-1 staining is weakly positive in non-neoplastic samples (200×).
