CYP2A6 staining of normal human endometrial tissues in the proliferative and secretory phases
When >10% of the constituting glandular epithelial cells were stained, the specimen was evaluated as CYP2A6-positive (+) and that with high intensity was judged as ++. The statistical significance of differences in the extent of staining in the different phases of the menstrual cycle was tested by Fisher's exact test (P < 0.001).
