On March 11, 2019, BC Children’s Hospital Research Institute hosted the Canadian Institutes of Health Research for the announcement of $1.7-million in funding for early career investigators conducting high impact research in maternal, reproductive, child and youth health. The recipients of these grants include Dr.
Normal fetal growth and development is a complex process with many points at which abnormality may occur. Triploidy and other chromosome abnormalities occur frequently in early pregnancy. Study of triploidy affords insights into the normal processes involved in successful pregnancy and ways in which those processes may be affected by chromosome abnormality. Study of triploid pregnancies yields information on intrauterine growth retardation, imprinting processes in placenta, function of the placenta and its component parts, and reasons for pregnancy losses.
