Differential levels of collagens in STICs. (A) Representative
multispectral staining of fimbriae for type I, type III, and type IV
collagens in benign (B), non-STIC (NS), or STIC (S) regions. Scale bar =
200 µm. (B) Quantification of epithelial MFI, stromal MFI, and
epithelial:stromal ratio (E:S ratio) of collagen I, collagen III, or
collagen IV in benign (B), non-STIC (NS), or STIC (S) regions. Data are
presented as a box plot indicating median and range; dashed line
demonstrates E:S = 1. *p< 0.05 for S compared with B
by Kruskal–Wallis test and Dunn’s multiple comparison posttest.
n=10 (B), 8 (NS), and 7 (S). (C) Epithelial MFI,
stromal MFI, and E:S ratio of patient-matched NS and S regions
(indicated by connecting lines). Dashed line demonstrates E:S = 1.
*p<0.05 by Wilcoxon matched-pair signed-rank
test. n=4 patients. Abbreviations: STIC, serous
intraepithelial carcinoma; MFI, mean fluorescent signal intensity.
