Galectin-1 overexpression in late secretory phase of eutopic endometrium and in endometriotic sites.

1a: Immunohistochemical expression of galectin-1 expression through the different phases of the menstrual cycle of the endometrium (A: proliferative, B: early secretory phase, C: late secretory phase) showing a higher expression pattern at the late secretory phase of the endometrium(C), *p<0.05. 1b: Western blot immunodetection of galectin-1 (14 kDa) protein expression in eutopic and ectopic endometrium. Galectin-1 is overexpressed in eutopic endometrium of endometriotic women (ee) when compared to eutopic endometrium of healthy women (he), *p<0.05 and galectin-1 shows an abundant expression in ectopic endometrium (e) when compared to eutopic endometrium of the same endometriotic women (ee), **p<0.01. GAPDH (37 KDa) was used as a house keeping gene.
