This is a biorepository and specimen collection program at the University of Minnesota in 2022 with support from the Department of Obstetrics, Gynecology and Women’s Health, the Department of Pediatrics, and the Institute for Diabetes, Obesity and Metabolism. The goal of this repository is to facilitate the systematic collection of maternal, placental, and neonatal specimens to support research efforts throughout the University of Minnesota community. These specimens contribute to ongoing research efforts to investigate how pregnancy impacts maternal and offspring health. All clinical specimens can be linked back to clinical data included within the UMOMs database. In addition to collecting fixed and frozen placental specimens, this repository also collects placentas for trophoblast isolation from healthy and complicated pregnancies. Maternal and cord blood samples available.

This is a clinical database at the University of Minnesota developed with support from the Department of Obstetrics, Gynecology and Women’s Health to facilitate investigations into how obstetrics care impacts maternal and neonatal outcomes.  This database contains clinical data related to antepartum, intrapartum, postpartum, and neonatal care for over 80,000 pregnant individuals and 110,000 deliveries from 2012-2023 at MHealth-Fairview, an academic-community health care partnership.  The database is updated two times each year. The data is maintained in a secure data environment facilitated by the CTSI Best Practices Integrated Informatics Core and all proposed studies undergo an abbreviated review and approval process.
