The role of kisspeptin and its cognate receptor GPR54 in normal and abnormal placentation
Poor invasion of trophoblast cells in early pregnancy has been associated with preeclampsia and intrauterine growth restriction as well as other adverse pregnancy outcomes such as miscarriage, preterm birth and intrauterine death. Hypertensive disorders of pregnancy, including pre-eclampsia are one …

The Role of the X-chromosomal Porcupine Homolog Gene in Mouse Development
… to X chromosome inactivation. In contrast to the placentation defect causing embryonic lethality of maternal allele mutants, deletion of the paternal allele caused variable fetal defects resulting in perinatal lethality with only rare survivors to adulthood. Both fetuses and adults represent a …

Biomarkers of disease : concentrations in the serum of women during natural and stimulated ovarian cycles and during early pregnancy
… events relating to ovulation and implantation/placentation. In addition, the study was able to investigate the possible erroneous crossing of clinical cut‐off values associated with disease due to other biological processes rather than the disease itself. total of 73 blood samples (10 women) …

The Effect of Exercise-induced Myokines on Placental Health and Function
… invasion, suggesting a possible role of SPARC in placentation.

Role of Histone Lysine Demethylase, KDM1B, in Trophoblast Stem Cell Self-Renewal and Differentiation
… research tool to study processes of early placentation in vitro. Despite the placenta’s central role in reproduction, our understanding of the regulatory networks that orchestrate TSC self-renewal and differentiation remains incomplete. In this project, I characterised an epigenetic …

Placental angiogenesis and immune-privilege in normal and pathological pregnancies
Proper placentation is a prerequisite for normal fetal development and investigations were conducted on expression and secretion profiles of GFs and CAMs. Studies on the pivotal angiogenic factors, angiogenin as well as PlGF, EGF and VEGF were conducted in normal and in pregnancies complicated by …

The influence of weaning age on growth and development of the baby pig and reproductive efficiency in the sow
… Uterine pathogens appeared to adversely affect placentation and/or embryonic survival.

Manipulating Embryonic Development and Endometrial Function in Ruminants
… to identify DEGs involved in implantation and placentation. This revealed 125 placentation DEGs in the endometrium, and 4 DEGs in conceptuses between obese and lean groups. A follow-up study was conducted to examine the abundance of transcripts with regulatory roles in embryogenesis. …

The embryology of Prionium serratum (L.f.) Drege ex E.Mey. (Juncaceae:Cyperales) and its implications for the phylogeny of Cyperales
… is absent. There are many ovules per locule and placentation is axile. The ovule is anatropous, bitegmic and crassinucellate. The embryo sac conforms to the Polygonum type of development. Endosperm formation is helobial and embryogeny is of the Onagrad type, Juncus variation. The mature embryo is …

The role of Ras-related C3 botulinum toxin substrate 1 (RAC1)-dependent pathway in the regulation of uterine function during early pregnancy
… and support the growth of the embryo before placentation. At the same time, new blood vessels begin to form in the maternal decidua from pre-existing vasculature. This process termed angiogenesis is critical for the establishment of the placenta and the maintenance of pregnancy. Although it …

A Peripartum Assessment of Nailfold Capillary Density in Women With Preeclampsia
… the inner myometrium layer of the uterus during placentation, resulting in the incomplete remodelling of the uterine spiral arteries. As a result, the placenta becomes hypoperfused and releases pathogenic factors in response. Pathogenic factors, such as reactive oxygen species (ROS) and soluble …

Esx1 Dosage Impacts Reproductive Fitness: Effects On Viability and Fertility
… duplicated or improperly inactivated, defects in placentation, growth and spermatogenesis are noted, suggesting tight control of X-chromosome gene dosage is important for reproduction. Esx1 is a mouse homeobox gene on the X-chromosome with expression limited to extraembryonic tissues and …

Development Of Trophoblast Lined Blood Spaces In The Mouse Placenta
… placenta will help us gain insights into human placentation and treatment of pregnancy related diseases.

Expression and secretion of basigin by human placental trophoblast cells occurs via microvesicle shedding and is a regulated process
… what the specific functions of BSG during early placentation may be. The main findings of our work are: 1) BSG protein is present in the human trophoblast throughout the first trimester of pregnancy; 2) human trophoblast-like cell lines in culture express BSG transcript variants -2, -3 and -4 and …

The role of ERα in the uterus during embryo implantation and in the ovary during ovarian tumorigenesis
… Both humans and rodents exhibit hemochorial placentation, an invasive form of embryo implantation which is characterized by intimate contact of the implanted embryo with maternal blood. Implantation is initiated when the embryo first attaches to the uterine epithelial cells and invades …

Mechanisms underlying establishment and maintenance of pregnancy
… phthalates affect different cell types during placentation.

Physical Factors Regulating Human Trophoblast Invasion
… pathogenesis of these diseases is defective placentation characterised by inadequate invasion of extravillous trophoblast (EVT) cells into the uterine decidua. This invasion is necessary to transform the uterine arteries, ensuring an adequate maternal blood supply into the intervillous space …
