Cytoplasm and nucleus of squamous epithelial cells in normal cervix and CIN3 exhibited moderate to strong maspin expression while SCC showed obviously weaker staining for maspin (P < 0.05) and tumor emboli in lymph nodes was the weakest (P < 0.05) (Figs. 1, 2, 3, 4, 5, 6). Here, SERPINB5 is linked to neoplasm.
