The research interests of the “Kingdom Group” synergize between a small group of CIHR-funded scientists based in the Lye Laboratory of the Samuel Lunenfeld Research Institute of Mount Sinai Hospital, the Department of Cardiology research group at Mount Sinai Hospital and the Placenta Clinic at the Special Pregnancy Program in the Ontario Power Generation Building, part of the Frances Bloomberg Centre for Women's and Infants' Health.  Our overall goal is to understand the molecular basis of placental dysfunction that mediates combinations of intrauterine growth restriction (IUGR), severe pre-eclampsia, stillbirth and abruption.  Our ability to study these conditions effectively in the laboratory is made possible by our BioBank Team at Mount Sinai Hospital. Our links between the Placenta Clinic and Cardiology allow us to study the maternal response to normal and abnormal placentation, assessed non-invasively in high-risk pregnancies. We are refining the choice of screening tools to effectively identify truly high-risk, from relatively-normal pregnancies, through our prospective “Placental Health Study in Nulliparous Women”.  This study began recruitment in February 2012.  We envision the study will continue for 5 years, include capture of the majority of placentas at delivery to thereby create a powerful research resource for future trainees.  Our group includes trainees across the full spectrum including pre-clinical and medical students, and clinical trainees.  New collaborative projects for 2013 include; in-vivo cardiovascular response of women at high risk of severe pre-eclampsia to Heparin (PI = Dr. John Kingdom) and the relationship between fetal cardiac function and brain perfusion in IUGR pregnancies (PI = Dr. Mike Seed, Hospital for Sick Children).
