Federal Grant Award Summary

Duke University received a $694,448 Project Grant from the National Institute of Child Health and Human Development (NICHD) under the Child Health and Human Development Extramural Research program (CFDA 93.865), effective July 1, 2026, through March 31, 2031. The award funds investigator-initiated research to analyze local and global response mechanisms in the placental syncytiotrophoblast (STB), a multinucleated tissue-sized cell that mediates nutrient exchange, fetal immunoprotection, and hormone production during pregnancy. The research focuses on understanding how distinct transcriptional programs within individual nuclei of the STB support diverse homeostatic and stress response functions, with emphasis on spatial patterning of nuclear identities and implications for placental diseases such as preeclampsia.

The funded research addresses critical knowledge gaps regarding nuclear heterogeneity within the STB cell and how differential nuclear organization contributes to placental function and dysfunction. Deliverables include scientific investigation into the mechanisms of nuclear identity development, spatial organization of distinct nuclear populations, and functional consequences of nuclear heterogeneity—findings intended to advance understanding of placental biology and inform treatment approaches for pregnancy-related complications stemming from improper placentation. Work will be conducted at Duke University's Durham, North Carolina facility through the Office of Research Administration.
