(A) Normal human endometrium specimens from subjects in proliferative and secretory phases were immunoblotted using EMP2 antisera. β-actin was used as a loading control. (B) Statistical analysis of EMP2 expression levels in proliferative (n = 3: subphase unspecified) and secretory (n = 3: one post-ovulatory day 3, one late, one unspecified) endometrial specimens from six independent patients. Data were analyzed using a 2-tailed, unpaired student t-test with a 95% confidence interval. *Changes in expression between the proliferative and secretory endometrium were significant, p = 0.038.
