complications such as miscarriage, preeclampsia and intrauterine growth restriction, the …

The placenta is the first organ to form during mammalian embryogenesis. Problems in its
formation and function underlie many aspects of early pregnancy loss and pregnancy …

The placenta of eutherian mammals is a remarkable biological structure. It is composed of
both zygote-derived and maternal cells, and mediates the complex interactions between the …

Placentation is a reproductive adaptation that permits fetal growth and development within
the protected confines of the female reproductive tract. Through this important role, the …

Genomic imprinting refers to an epigenetic marking of genes that results in monoallelic
expression. This parent-of-origin dependent phenomenon is a notable exception to the laws …

Genomic imprinting in gametogenesis marks a subset of mammalian genes for parent‐of‐
origin‐dependent monoallelic expression in the offspring. Embryological and classical …

Genes can be transcribed from within chromosome territories; however, the major
histocompatibilty complex locus has been reported extending away from chromosome …

Comparing the placenta from one species to another can be a challenging task. On one
hand, the gross anatomy of the placenta is at least superficially rather different among …

Villous cytotrophoblasts are epithelial stem cells of the early human placenta, able to
differentiate either into syncytiotrophoblasts in floating chorionic villi or extravillous …

The placenta is comprised of an inner vascular network covered by an outer epithelium,
called trophoblast, all designed to promote the delivery of nutrients to the fetus. Several …
