Fig 1. Examples of immunohistochemical staining for ALDH1 in endometrial lesions.

Fig 1

(A) Immunohistochemical examination of ALDH1 expression in normal endometrium (a), EH without atypia (b), AH (c), grade 1 EmAC (d), grade 2 EmAC (e), grade 3 EmAC (f), SC (g), CC (h), and MC (i). (B) Semiquantitative Comparison of ALDH1 Immunostaining Scores Between Normal Endometrium, EH without Atypia, AH, and Type I, and Type II EC. Normal endometrium vs. Type I EC, p<0.001***; EH without atypia vs. Type I EC, p<0.001***; AH vs. Type I EC, p<0.05*.
