XCL1 and squamous cell carcinoma: Of note, XCL1 was predominantly expressed in cancer cells showing adenocarcinoma morphology and dysplastic cells in the submucosa glands, while CD160 could be expressed in both squamous carcinoma and adenocarcinoma cells (Fig. 2h, Supplementary Fig. 8c) as well as in the proliferative and dysplastic cells of the submucosa glands (Supplementary Figs. 8d and 11).
