Table 2 WFA-staining scores in ovarian endometriotic cysts (n = 16) and proliferative-phase eutopic endometrium samples (n = 20)

From: Wisteria floribunda agglutinin-binding glycan expression is decreased in endometriomata

  Epithelial component Stromal component

  1. The WFA-staining intensity was evaluated separately for the epithelial component and the stromal component and stratified as follows: 0 (negative), 1 (weak), 2 (moderate), and 3 (strong). Two gynecologists (K. K. and M. Y.) scored all samples independently, and discrepancies were resolved by simultaneous examination. *p < 0.05 vs. eutopic endometrium (Student’s t-test).
