aMaximal 18 MZ and 10 DZ twins per tissue. AGA, appropriate for gestational age; CBMC, cord blood mononuclear cell; DZ, dizygotic twin; FDR, false discovery rate; HELP, HpaII tiny fragment Enrichment by Ligation-mediated PCR assay; HM27, HumanMethylation27 BeadChip; IUGR, intra-uterine growth retarded; MZ, monozygotic twins; UVEC, umbilical vascular endothelial cell. |
