Impact of the number of previous embryo implantation failures on IVF/ICSI-ET pregnancy outcomes in patients younger than 40 years: a retrospective cohort study

open access: yesFrontiers in Endocrinology, 2023
ObjectiveThe objective of this study was to examine the influence of repeated embryo implantation failures on pregnancy outcomes among patients under 40 years of age undergoing in vitro fertilization/intracytoplasmic sperm injection embryo transfer (IVF ...

The effects of aging on molecular modulators of human embryo implantation

open access: yesiScience, 2021
Summary: Advancing age has a negative impact on female fertility. As implantation rates decline during the normal maternal life course, age-related, embryonic factors are altered and our inability to monitor these factors in an unbiased genome-wide ...

Human Blastocyst Secreted microRNA Regulate Endometrial Epithelial Cell Adhesion

open access: yesEBioMedicine, 2015
Successful embryo implantation requires synchronous development and communication between the blastocyst and the endometrium, however the mechanisms of communication in humans are virtually unknown.

Hormonal Replacement Treatment for Frozen-Thawed Embryo Transfer With or Without GnRH Agonist Pretreatment: A Retrospective Cohort Study Stratified by Times of Embryo Implantation Failures

open access: yesFrontiers in Endocrinology, 2022
ObjectiveTo evaluate the efficacy of the long-acting gonadotropin-releasing hormone agonist (GnRH-a) administration before hormone replacement treatment for frozen-thawed embryo transfer in women with different times of embryo implantation failures ...

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

open access: yes, 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]

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

Microbead Implantation in the Zebrafish Embryo [PDF]

open access: yesJournal of Visualized Experiments, 2015
The zebrafish has emerged as a valuable genetic model system for the study of developmental biology and disease. Zebrafish share a high degree of genomic conservation, as well as similarities in cellular, molecular, and physiological processes, with other vertebrates including humans.

Alternative Splicing in Embryo Implantation. [PDF]

open access: yesMatern Fetal Med
Abstract Alternative splicing (AS) is a crucial process that produces functionally distinct proteins from a single gene, depending on the developmental or physiological state of cells in multicellular organisms. It plays a significant role in cellular proliferation, survival, and differentiation, including embryonic development,

The evolution of embryo implantation

open access: yesThe 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.

Coordination Mechanisms of Mammalian Embryo Implantation [PDF]

open access: yes, 2023
A direct interaction between the extraembryonic and the uterine tissues during embryo implantation generates a unique biomechanical context for the blastocyst.
