Building Principles for Constructing a Mammalian Blastocyst Embryo
Biology, 2018 The self-organisation of a fertilised egg to form a blastocyst structure, which consists of three distinct cell lineages (trophoblast, epiblast and hypoblast) arranged around an off-centre cavity, is unique to mammals.

Terrestrial Planets Formation around Circumbinary Habitable Zone: Inward Migration in the Planetesimal Swarm [PDF]
, 2012 According to the core accretion theory, circumbinary embryos can form only beyond a critical semimajor axis (CSMA). However, due to the relatively high density of solid materials in the inner disk, significant amount of small planetesimals must exist in the inner zone when embryos were forming outside this CSMA.

Embryo metabolism : what does it really mean? [PDF]
, 2015 The study of early embryo metabolism has fascinated researchers in the field for nearly a century. Herein, we give a brief account of the general features of embryo metabolism and some consideration of the research performed to reach such conclusions. It

Cilia, calcium and the basis of left-right asymmetry
BMC Biology, 2012 The clockwise rotation of cilia in the developing mammalian embryo drives a leftward flow of liquid; this genetically regulated biophysical force specifies left-right asymmetry of the mammalian body.

The growth of planetary embryos: orderly, runaway, or oligarchic? [PDF]
Astron.J. 125 (2003) 942, 2002 We consider the growth of a protoplanetary embryo embedded in a planetesimal disk. We take into account the dynamical evolution of the disk caused by (1) planetesimal-planetesimal interactions, which increase random motions and smooth gradients in the disk, and (2) gravitational scattering of planetesimals by the embryo, which tends to heat up the disk

Lack of RNA-DNA oligonucleotide (chimeraplast) mutagenic activity in mouse embryos [PDF]
, 2005 There are numerous reports of the use of RNA-DNA oligonucleoticles (chimeraplasts) to correct point mutations in vitro and in vivo, including the human apolipoprotein E gene (ApoE).

The dynamics of morphogenesis in stem cell-based embryology: Novel insights for symmetry breaking [PDF]
, 2020 Breaking embryonic symmetry is an essential prerequisite to shape the initially symmetric embryo into a highly organized body plan that serves as the blueprint of the adult organism.

Repeats as global DNA methylation marker in bovine preimplantation embryos [PDF]
, 2017 DNA methylation undergoes dynamic changes and is a crucial part of the epigenetic regulation during mammalian early development. To determine the DNA methylation levels in bovine embryos, we applied a bisulfite sequencing based method aimed at repetitive

EmbryosFormer: Deformable Transformer and Collaborative Encoding-Decoding for Embryos Stage Development Classification [PDF]
arXiv, 2022 The timing of cell divisions in early embryos during the In-Vitro Fertilization (IVF) process is a key predictor of embryo viability. However, observing cell divisions in Time-Lapse Monitoring (TLM) is a time-consuming process and highly depends on experts.
