Figure 1

Representative Notch1 immunohistochemical staining in samples with different histological alterations. Notch1 protein was mainly expressed in cytoplasm of esophageal cells. Intense staining of Notch1 was mainly present in normal esophagus, and metaplastic columnar cells mainly exhibited negative staining (arrows). Scale bar in the figure is 40 μm. Magnified figures were shown in the right side.
