2. Figure 1
Immunohistochemistry of aquaporins (AQPs) in eutopic endometria. Representative negative immunostaining of AQPs in a midsecretory phase (control group) (A, E, I) and positive immunostaining in early proliferative phase (EP) (B, F, J), late proliferative phase (LP) (C, G, K), and secretory phase (SP) (D, H, L). Magnification ×200.

Immunohistochemistry of AQPs in ectopic endometria. Representative negative immunostaining of AQPs in a midsecretory phase (control group) (A, E, I) and positive immunostaining in EP (B, F, J), LP (C, G, K), and SP (D, H, L).Magnification ×200. Abbreviations as in Figure 1.

4. Figure 3
Incidence of positive immunostaining of AQPs in various phases of the menstrual cycle. No significant difference in AQP-2, -5, and -8 expression in eutopic endometrium or in ectopic endometrium from women with endometriomas. PP = proliferative phase, SP = secretory phase. PP vs. SP in EuAQP-2: P=.768. PP vs. SP in EuAQP-5: P=.052. PP vs. SP in EuAQP-8: P=.299. PP vs. SP in EcAQP-2: P=.215. PP vs. SP in EcAQP-5: P=.091. PP vs. SP in EcAQP-8: P=.284. EcAQP=aquaporin expressed in ectopic endometrium; EuAQP=aquaporin expressed in eutopic endometrium; other abbreviations as in Figure 1.

5. Figure 4
Comparison of AQP expression in 70 eutopic and ectopic endometrial tissues. Significant difference in AQP-2, -5, and -8 expression between eutopic and ectopic endometrium from women with endometriomas: EuAQP-2 vs. EcAQP-2: P<.001. EuAQP-5 vs. EcAQP-5: P=.004. EuAQP-8 vs. EcAQP-8: P=.001. Abbreviations as in Figures 1 and 4.

6. Figure 5
Expression of aquaporins (AQP) 2, 5, and 8 in eutopic endometria (A–C) and ectopic endometria (D–F). Expression levels of endometrial AQP-2, -5, and -8 are lower in ectopic group than in eutopic group. Magnification v×400.
