Asynchronous fate decisions by single cells collectively ensure consistent lineage composition in the mouse blastocyst

Nature Communications, 2016
Intercellular communication is essential to coordinate the behaviour of individual cells during organismal development. The preimplantation mammalian embryo is a paradigm of tissue self-organization and regulative development; however, the cellular basis

Role of the Mitochondrial Genome During Early Development in Mice [PDF]

, 1973
The role of the mitochondrial genome in early development and differentiation was studied in mouse embryos cultured in vitro from the two to four cell stage to the blastocyst (about 100 cells).

ADAR1 as a Placental Innate Immune Rheostat Sustaining the Homeostatic Balance of Intrinsic Interferon Response at the Maternal‐Fetal Interface

Advanced Science, EarlyView.
This study reveals that ADAR1, an RNA‐editing enzyme, fine‐tunes immune responses in the placenta by preventing the accumulation of immunogenic double‐stranded RNAs (dsRNAs) from interferon‐stimulated genes. The loss of ADAR1 in the placenta leads to excessive interferon signaling restricted to the junctional zone, disrupting placental development and ...

Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans

Topics in Cognitive Science, EarlyView., 2023
Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not

Clinical Relevance of Secreted Small Noncoding RNAs in an Embryo Implantation Potential Prediction at Morula and Blastocyst Development Stages

Life, 2021
Despite the improvements in biotechnological approaches and the selection of controlled ovarian hyperstimulation protocols, the resulting pregnancy rate from in vitro fertilization (IVF) protocols still does not exceed 30–40%.

The effect of leukaemia inhibitory factor (LIF) on bovine embryo development in vitro : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science at Massey University [PDF]

, 1995
The aim of the study was to investigate the effect of Leukaemia Inhibitory Factor (LIF) either during in vitro maturation (IVM) or in vitro culture (IVC) on bovine embryo development. Three main experiments were conducted using oocytes aspirated from 2-8

The Critical Role of Enhanced OXPHOS and Mitochondrial Hyperpolarization in Simulated Microgravity‐Induced Oocyte Maturation Arrest

Advanced Science, EarlyView.
Simulated microgravity induces distinct mitochondrial hyperactivation patterns‐elevated OXPHOS and MMP‐which accelerate meiosis without SAC failure but delays MTOC coalescence, leading to spindle defects and meiotic arrest. Prolonging M‐phase restores MTOC assembly and oocyte maturation.

Cytokines That Serve as Embryokines in Cattle

Animals, 2021
The term “embryokine” has been used to denote molecules produced by the endometrium, oviduct, or by embryo itself that will influence embryo development. Several cytokines have been identified as embryokines in cattle and other mammals.

BHLHE40 Cooperates with GATA2/3 to Control Human Syncytiotrophoblast Lineage Differentiation

Advanced Science, EarlyView.
BHLHE40 interacts directly with GATA2 and GATA3 and co‐occupies genomic loci critical for STB differentiation and function. BHLHE40 also affects GATA2/3 binding at enhancer and promoter regions. Moreover, BHLHE40 is potentially involved in genome‐wide remodeling of H3K4me3 and H3K27ac chromatin landscapes through GATA2/3 recruitment, activating ...

The Effect of Prolonged Culture of Chromosomally Abnormal Human Embryos on The Rate of Diploid Cells [PDF]

International Journal of Fertility and Sterility, 2016
Background A decrease in aneuploidy rate following a prolonged co-culture of human blastocysts has been reported. As co-culture is not routinely used in assisted reproductive technology, the present study aimed to evaluate the effect of the prolonged ...
