The physiological significance of insemination in programming pregnancy outcome [PDF]

, 2006
The cellular and molecular environment of the uterus during the pre - and peri - implantation period of early pregnancy is critical for implantation success and optimal fetal and placental development.

Telomere lengths in human oocytes, cleavage stage embryos and blastocysts [PDF]

, 2010
Telomeres are repeated sequences that protect the ends of chromosomes and harbour DNA-repair proteins. Telomeres shorten during each cell division in the absence of telomerase.

Proteomic profiling of human uterine extracellular vesicles reveal dynamic regulation of key players of embryo implantation and fertility during menstrual cycle

Proteomics, 2021
Endometrial extracellular vesicles (EVs) are emerging as important players in reproductive biology. However, how their proteome is regulated throughout the menstrual cycle is not known.

Uterine luminal-derived extracellular vesicles: potential nanomaterials to improve embryo implantation

Journal of Nanobiotechnology, 2023
Most pregnancy losses worldwide are caused by implantation failure for which there is a lack of effective therapeutics. Extracellular vesicles are considered potential endogenous nanomedicines because of their unique biological functions.

The evolution of embryo implantation

The International Journal of Developmental Biology, 2014
Embryo implantation varies widely in placental mammals. We review this variation in mammals with a special focus on two features: the depth of implantation and embryonic diapause. We discuss the two major types of implantation depth, superficial and interstitial, and map this character on a well-resolved molecular phylogenetic tree of placental mammals.

Prediction model for day 3 embryo implantation potential based on metabolites in spent embryo culture medium

BMC Pregnancy and Childbirth, 2023
Background Metabolites in spent embryo culture medium correlate with the embryo’s viability. However, there is no widely accepted method using metabolite dada to predict successful implantation.

Gene Expression Profiling of Corpus luteum Reveals Important Insights about Early Pregnancy in Domestic Sheep [PDF]

, 2020
The majority of pregnancy loss in ruminants occurs during the preimplantation stage, which is thus the most critical period determining reproductive success. Here, we performed a comparative transcriptome study by sequencing total mRNA from corpus luteum

Assessment of Embryo-Induced Transcriptomic Changes in Hamster Uterus Using RNA-Seq

Cellular Physiology and Biochemistry, 2018
Background/Aims: The mouse is widely used as an animal model for studying human embryo implantation. However, the mouse is unique in that both ovarian progesterone and estrogen are critical to implantation, whereas in the majority of species (e.g.

Physiologic Events of Embryo Implantation and Decidualization in Human and Non-Human Primates

International Journal of Molecular Sciences, 2020
Reproduction is a fundamental process for the preservation of the human species. This process requires a sequence of orchestrated events that are necessary for a successful pregnancy. Two of the most critical steps in the establishment of human pregnancy

Deciphering mouse uterine receptivity for embryo implantation at single‐cell resolution

Cell Proliferation, 2021
Mice are widely used as an animal model for studying human uterine receptivity for embryo implantation. Although transcriptional changes related to mouse uterine receptivity have been determined by using bulk RNA‐seq, the data are of limited value ...
