Figure 1. Gas6 and Axl expression in ESCC tissues. (A) HE staining; NC: nontumor esophageal tissue, ESCC: esophageal squamous cell carcinoma tissue. (B) Immunohistochemical assessment of Gas6 expression in NC and ESCC tissues. (C) Immunofluorescence assessment of Axl expression in NC and ESCC tissues; DAPI-labeled nuclei are in blue, and the merge imaged shows Axl and nuclear overlap. Scale bars indicate 50 μm.
