E-cadherin expression in the ovarian surface epithelial cells. Immunohistochemical staining for E-cadherin in a paraffin-embedded ovary section (A) and whole ovaries (B, C). The asterisks indicate groups of epithelial cells in which E-cadherin is expressed at a low level. Distinct patches of ovarian surface epithelial cells with variable levels of E-cadherin expression are detected by whole ovary immunohistochemistry (C).
