abstract
In the gravid uterus of the ewe, 70-120 placentomes composed of a fetal component (cotyledon) and a maternal component (caruncle) function as individual placental units where maternal to fetal nutrient transfer occurs. Further, the morphological conversion of ovine placentomes from type A (found early in gestation) to more advanced forms (B, C, or D types) increases with the advancement of gestation. To our knowledge, nobody has evaluated the changes in the three dimensional structure of the cotyledonary vasculature as the placentome advances from A to D forms. Further, nobody has evaluated the changes that may occur in this vascular bed in response to maternal obesity. Using latex vascular casts, we visualized the cotyledonary vascular beds of type A, B, C, and D placentomes in a normal pregnancy and found that the cotyledonary vascular beds become larger and more organized as the placentome develops. In the obese ewes the cotyledonary beds of the A type placentomes were markedly less branched and organized than type A placentomes from control pregnancies, resulting in a less dense vascular bed, and suggesting decreased blood flow through this bed in obese ewes.
