An in vitro stem cell model of human epiblast and yolk sac interaction

open access: yeseLife, 2021
Human embryogenesis entails complex signalling interactions between embryonic and extra-embryonic cells. However, how extra-embryonic cells direct morphogenesis within the human embryo remains largely unknown due to a lack of relevant stem cell models ...

Cell arrest and cell death in mammalian preimplantation development [PDF]

open access: yes, 2011
The causes, modes, biological role and prospective significance of cell death in preimplantation development in humans and other mammals are still poorly understood.

A single cell characterisation of human embryogenesis identifies pluripotency transitions and putative anterior hypoblast centre

open access: yesNature Communications, 2021
Single cell analysis of early human embryos identifies key changes in pluripotency, the requirement of FGF signalling for embryo survival, and defines a putative anterior-like region of hypoblast cells, providing insights into how early human development

Stain-free detection of embryo polarization using deep learning

open access: yesScientific Reports, 2022
Polarization of the mammalian embryo at the right developmental time is critical for its development to term and would be valuable in assessing the potential of human embryos.

IVEN: A quantitative tool to describe 3D cell position and neighbourhood reveals architectural changes in FGF4-treated preimplantation embryos.

open access: yesPLoS Biology, 2021
Architectural changes at the cellular and organism level are integral and necessary to successful development and growth. During mammalian preimplantation development, cells reduce in size and the architecture of the embryo changes significantly.

Epithelial-Mesenchymal Transition Drives Three-Dimensional Morphogenesis in Mammalian Early Development

open access: yesFrontiers in Cell and Developmental Biology, 2021
From fertilization to onset of gastrulation, a mammalian embryo goes through several rounds of cellular morphogenesis resembling phenomena of epithelial-mesenchymal transition (EMT) and mesenchymal-epithelial transition (MET), collectively referred to as

Neddylation Inhibition Causes Impaired Mouse Embryo Quality and Blastocyst Hatching Failure Through Elevated Oxidative Stress and Reduced IL-1β

open access: yesFrontiers in Immunology, 2022
Mammalian blastocyst hatching is an essential prerequisite for successful embryo implantation. As the rate-limiting step of current assisted reproductive technology, understanding the key factors regulating blastocyst hatching would be significantly ...

A hexa-species transcriptome atlas of mammalian embryogenesis delineates metabolic regulation across three different implantation modes

open access: yesNature Communications, 2022
Mammalian embryogenesis relies on glycolysis and oxidative phosphorylation, but understanding of the dynamics of metabolic regulation in the postimplantation embryo in vivo remains elusive.

Human embryos cultured in vitro to 14 days [PDF]

open access: yesOpen Biology, 2017
We know a great deal about the development of the mammalian embryo until the time that the blastocyst implants into the uterus. With model organisms such as the mouse, we have also developed a considerable understanding of development immediately around ...

Post-Translational Modifications in Oocyte Maturation and Embryo Development

open access: yesFrontiers in Cell and Developmental Biology, 2021
Mammalian oocyte maturation and embryo development are unique biological processes regulated by various modifications. Since de novo mRNA transcription is absent during oocyte meiosis, protein-level regulation, especially post-translational modification (
