Immunostaining for CCL16 and CCL21 in eutopic and ectopic tissue from control and endometriosis subjects. Staining intensity for (A) CCL16 and (B) CCL21 in glandular epithelium of normal mid secretory endometrium (n = 12) (■) and in glandular epithelium in paired eutopic (▲) and ectopic (▼) endometrium from women with endometriosis (n = 10), also in the mid-secretory phase of the menstrual cycle. Open symbols represent subjects whose samples were used in the gene array study. Staining intensity was scored on a scale of 0 (no stain) to 4 (intense stain). Scores are shown for individual samples. Bars represent mean values. * denotes a statistical difference between 2 samples from the same patients (P = 0.047, Wilcoxon Matched-Pairs Signed-Ranks Test).
