Real-time PCR quantitation of CCL16 and CCL21 mRNA expression in control and endometriosis subjects. (A) mRNA expression of CCL16 and (B) CCL21 was measured in glandular RNA samples from individuals in control (■) and endometriosis cohorts (■, ●, ▲ representing the 3 patients' individual data). Data is presented as relative units where chemokine expression has been normalized to 18S RNA expression for each sample (n = 3 per group, RT-PCR performed in duplicates). The average value for each subject group is indicated with a horizontal line. * denotes a statistically significant difference between the 2 groups (P = 0.049, Mann-Whitney U-test).
