This article builds on feminist scholarship on new biologies and the body to describe the temporal politics of epigenetic research related to the human placenta. Drawing on interviews with scientists and observations at conferences and in laboratories, we argue that epigenetic research simultaneously positions placenta tissue as a way back into maternal and fetal bodies following birth, as a lens onto children’s future well-being, and as a bankable resource for ongoing research. Our findings reflect how developmental models of health have (...) helped recast the placenta as an agential organ that is uniquely responsive to environments during pregnancy and capable of embodying biological evidence about the effects of in utero experiences after birth. We develop the concept of ‘recursive embodiment’ to describe how placenta epigenetics is reimagining relationships between bodies and environments across developmental, epigenetic, and generational time, and the impacts this has for experiences of pregnancy and responsibilities related to children’s health.

The founding of the Carnegie Institute’s Department of Embryology in 1913, alongside its systematization of embryo staging, contributed to the mechanization of developmental stages of embryo growth in the early 20th century. For a brief period in the middle of the century, attention to the detailed interrelation between embryo development and time made pre-existing ideas about pregnancy ends less determinative of ideas about that developmental course. However, the turn to the genetic scale led to the disappearance of this attention, replaced (...) by a sense of biological life as seamlessly scripted. This study examines the history of what I refer to as temporal attention: attention to the live, unfolding potentialities within vital matter. The reintroduction of temporal attention to discussions of development allows us to more fully consider non-human vitality and the experiences of beings that house or otherwise intimately intersect with that vital tissue, regardless of outcomes.

The placenta has played an important role in feminist theories of subjectivity; however, the placenta of feminist theory has been the fully functional placenta of what is considered a successful full-term pregnancy. Pregnancy loss, a topic that has been generally overlooked within feminist scholarship, is absent from feminist theories of the placenta. This article uses early placental development, particularly development that takes place before the placenta becomes fully functional as an organ for hormone production and interchange, as a space through (...) which to consider theorising subjectivity, reproduction and relation through pregnancy loss. In so doing, I argue that turning our attention to the placenta’s early development, regardless of outcomes, allows us to reimagine the role of process for feminist theories of subjectivity while also making room for a wider array of pregnancy outcomes, reinvigorating our ability to think about relations and models of hospitality that do not end as we might imagine.
