EpCAM and MMP7 expression correlates in vivo in primary human samples. Serial cryosections of normal and dysplastic mucosa, and head and neck carcinoma samples were stained with EpCAM- or MMP7-specific antibodies (red staining). Shown are representative examples. EpCAM and MMP7 pattern and expression levels tightly correlated, even at the single-cell levels (exemplified with *).
