Cellular retinol-binding protein-1 expression in endometrial stromal cells: physiopathological and diagnostic implications

and diagnostic implications Aims: Cellular retinol-binding protein-1 (CRBP-1) con-tributes to the maintenance of the differentiated state of the endometrium through retinol bioavailability regu-lation. The aim was to analyse CRBP-1 expression in endometrial stromal cells at eutopic and ectopic sites in different physiopathological conditions. Methods and results: Antibodies to CRBP-1, CD10 and a-smooth muscle actin were applied to proliferative (n 10), secretory (n 9) and atrophic (n 7)
