Expression of E- and N-cadherin and CD44 in endometrium and hydrosalpinges from infertile women.

In this prospective comparative study, compared with fertile control subjects (n = 12), infertile patients with hydrosalpinx (n = 18) had lower E-cadherin and a trend toward decreased N-cadherin H-scores in the endometrium (3.6 +/- 0.6 vs. 2.4 +/- 0.8 and 0.57 +/- 1.0 vs. 0.52 +/- 0.5, respectively). In hydrosalpinx, epithelial N-cadherin expression was discontinuous and disappeared in atrophic patches. (Fertil Steril (R) 2010;94:2909-12. (c) 2010 by American Society for Reproductive Medicine.)
