Figure 1 In vitro RT-PCR of IL-6. The lanes show the following: lane a, separation of a molecular weight marker; lanes b–d, IL-6 amplicon in human endometrium, endometriosis, and placenta as a positive control with primers P1 and P2; lanes e–g, IL-6 amplicon in human endometrium, endometriosis, and placenta as a positive control with primed in situ labeling primer P3 and P4; lane h, negative control, omitting RT; and lanes i–k, glyceraldehyde-3 phosphate dehydrogenase amplicon in human endometrium, endometriosis, and placenta tissue.

Figure 2 (a) Demonstration of IL-6 expression levels in endometriosis tissue (Es, n = 6), in endometrium (Em, n = 6), in placenta as positive control (C1–C3, dilutions of 1:5, 1:50, and 1:500), and in H2O as negative control (C4). (b) Comparison of relative IL-6 expression between endometriosis and non-endometriosis patients (each n = 6; P=.03, Wilcoxon test).

Figure 3 Detection of IL-6 by in situ RT-PCR technique. (a) Endometrium (magnification, ×200), (b) endometriosis (magnification, ×400), (c, d) tonsil and placenta as positive control (magnification, ×400), and (e) endometriotic tissue without primer as negative control (magnification, ×200). EP = epithelial cells; ST = stroma cells; PC = plasma cells; LC = lymphocytes; SC = syncytiotrophoblasts; and HC = fetal Hofbauer cells.
