(A) Immunostaining of c-fos protein in different groups of endometria. A, Normal eutopic endometrium; B, eutopic endometrium from endometriotic patients; C, ectopic endometrium from endometriotic patients; and D, negative control. Original magnification: ×400. (B) H-SCORE of c-fos protein staining in different groups of endometria. ∗P<.05, compared with normal eutopic endometria.

Western blotting analysis of c-fos and MMP-9 protein expression in different groups of endometria throughout the menstrual cycle. (A, C) Expression of c-fos and MMP-9 proteins in endometria from the patients with or without endometriosis, respectively. A, Eutopic endometrium at the proliferative phase from the endometriotic patients; B, ectopic endometrium at the proliferative phase; C, eutopic endometrium at the proliferative phase from the controls; D, eutopic endometrium at the secretory phase from the endometriotic patients; E, ectopic endometrium at the secretory phase; F, eutopic endometrium at the secretory phase from the controls. (B, D) Summary data of c-fos and MMP-9 protein expression, respectively. Euto, eutopic endometria from the endometriotic patients; Ecto, ectopic endometria; Endo, eutopic endometria from the controls. ∗P<.05, compared with normal eutopic endometria at the same menstrual phase. #P<.05, ##P<.01, compared with the corresponding secretory endometria, respectively.
