Cord blood buffy coat DNA methylation is comparable to whole cord blood methylation

ABSTRACT: Cord blood DNA methylation is associated with numerous health outcomes and environmental exposures. Whole cord blood DNA reflects all nucleated blood cell types, while centrifuging whole blood separates red blood cells by generating a white blood cell buffy coat. Both sample types are used in DNA methylation studies. Cell types have unique methylation patterns and processing can impact cell distributions, which may influence comparability. To evaluate differences in cell composition and DNA methylation between buffy coat and whole cord blood samples, cord blood DNA methylation was measured with the Infinium EPIC BeadChip (Illumina) in 8 individuals, each contributing buffy coat and whole blood samples.

Epigenome analysis of cord blood DNA from infants born into the UPBEAT study

Project description:Genome-wide DNA methylation profiling of umbilical cord blood buffy coat DNA samples. The Illumina Infinium MethylationEPIC array was used to obtain DNA methylation profiles across approximately 850,000 CpGs. Samples included 557 cord blood samples born to obese women in the UPBEAT trial, with and without gestational diabetes mellitus (GDM), to determine the association between maternal GDM and hyperglycaemia during pregnancy on the methylation in the infant.

Smaller stature in childhood following assisted reproductive technologies (ART) is not explained by parental or gestational factors, early childhood environment, or fetal DNA methylation [GUSTO_buffy_coat]

Project description:As part of an investigation on contributors to offspring size following assisted reproduction, we investigated maternal mid-/late-pregnancy peripheral blood buffy coat DNA methylation at 240 CpGs previously associated with maternal pregnancy morbidity or offspring growth across various tissues. Illumina Infinium MethylationEPIC BeadChip was used to obtain DNA methylation profiles in previously frozen buffy coat samples from 70 women who conceived via assisted reproduction technologies and gave live births and 845 women who spotaneously conceived and gave live births.
