Endometrial stromal cells of women with recurrent miscarriage fail to discriminate between high- and low-quality human embryos [PDF]

, 2012
Background The aetiology of recurrent miscarriage (RM) remains largely unexplained. Women with RM have a shorter time to pregnancy interval than normally fertile women, which may be due to more frequent implantation of non-viable embryos.

Disordered IL-33/ST2 activation in decidualizing stromal cells prolongs uterine receptivity in women with recurrent pregnancy loss [PDF]

, 2012
Decidualization renders the endometrium transiently receptive to an implanting blastocyst although the underlying mechanisms remain incompletely understood.

Cell lineage specific distribution of H3K27 trimethylation accumulation in an in vitro model for human implantation [PDF]

, 2012
Female mammals inactivate one of their two X-chromosomes to compensate for the difference in gene-dosage with males that have just one X-chromosome. X-chromosome inactivation is initiated by the expression of the non-coding RNA Xist, which coats the X ...

Control of human endometrial stromal cell motility by PDGF-BB, HB-EGF and trophoblast-secreted factors [PDF]

, 2013
Human implantation involves extensive tissue remodeling at the fetal-maternal interface. It is becoming increasingly evident that not only trophoblast, but also decidualizing endometrial stromal cells are inherently motile and invasive, and likely ...

Secreted MicroRNA to Predict Embryo Implantation Outcome: From Research to Clinical Diagnostic Application

Frontiers in Cell and Developmental Biology, 2020
Embryo implantation failure is considered a leading cause of infertility and a significant bottleneck for in vitro fertilization (IVF) treatment. Confirmed factors that lead to implantation failure involve unhealthy embryos, unreceptive endometrium, and ...

The Complicated Effects of Extracellular Vesicles and Their Cargos on Embryo Implantation

Frontiers in Endocrinology, 2021
As a rate-limiting step in pregnancy, embryo implantation is highly dependent on intercellular communication. Extracellular vesicles (EVs) are newly identified to be important in the course of intercellular communication.

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.

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.

Evolutionary divergence of embryo implantation in primates. [PDF]

, 2022
Implantation of the conceptus into the uterus is absolutely essential for successful embryo development. In humans, our understanding of this process has remained rudimentary owing to the inaccessibility of early implantation stages.
