Title
Fetal microchimerism and maternal health: a molecular
epidemiological approach (Research)
Abstract
Epidemiology is the study of the patterns, causes and effects of health and disease conditions in
defined populations. An advantage of epidemiologic research is that it looks at people in their
'natural' environment, and looks to explain the differences between people within a population.
When women are pregnant, cells from her unborn child enter the maternal bloodstream, and
remain present in her body for decades after delivery. There is a huge variety in levels of fetal cells
present in mothers. I aim to assess this variability within the ENVIRONAGE birth cohort. This
cohort consists currently of 1200 mother-newborn pairs and enrollment is still ongoing. Structured
follow-up measures of cardiovascular phenotypes in both mothers and children at age 4 of the
child have begun (183 participants so far). I will unravel the differences in fetal cells in mothers
and determine whether these fetal cells are linked with maternal stress indicators. For this
purpose, I analyze stress at the physiologic level (molecular markers) and at the psychological level
(questionnaires). If FMC is indeed associated with lower maternal stress levels, this could influence
her ability to age well, and aid in the prevention of age-related diseases such as cardiovascular
disease. I will study the decline of presence of fetal cells in the mothers over time, and investigate
whether this is associated with cardiovascular phenotypes of both the micro- and macrocirculation
