M1 = maternal blood from 1st collection at enrollment, M2 = maternal blood from 2nd collection at 32nd wk of pregnancy and M3 = maternal blood from 3rd collection at delivery.
*, #, † and δ represent significant activity difference from M1, M2, M3 and cord blood, respectively (p-value < 0.05) using paired-sample t-test.
