Accretion of Uranus and Neptune from inward-migrating planetary embryos blocked by Jupiter and Saturn [PDF]
, 2015 Reproducing Uranus and Neptune remains a challenge for simulations of solar system formation. The ice giants' peculiar obliquities suggest that they both suffered giant collisions during their formation. Thus, there must have been an epoch of accretion dominated by collisions among large planetary embryos in the primordial outer solar system.

Atlas-based automated detection of swim bladder in Medaka embryo [PDF]
arXiv, 2019 Fish embryo models are increasingly being used both for the assessment of chemicals efficacy and potential toxicity. This article proposes a methodology to automatically detect the swim bladder on 2D images of Medaka fish embryos seen either in dorsal view or in lateral view. After embryo segmentation and for each studied orientation, the method builds

Deep learning mediated single time-point image-based prediction of embryo developmental outcome at the cleavage stage [PDF]
arXiv, 2020 In conventional clinical in-vitro fertilization practices embryos are transferred either at the cleavage or blastocyst stages of development. Cleavage stage transfers, particularly, are beneficial for patients with relatively poor prognosis and at fertility centers in resource-limited settings where there is a higher chance of developmental failure in ...

Bmp4 is required for the generation of primordial germ cells in the mouse embryo.
Genes & Development, 1999 In many organisms the allocation of primordial germ cells (PGCs) is determined by the inheritance of maternal factors deposited in the egg. However, in mammals, inductive cell interactions are required around gastrulation to establish the germ line. Here,

Time to take human embryo culture seriously.
Human Reproduction, 2016 STUDY QUESTION Is it important that end-users know the composition of human embryo culture media? SUMMARY ANSWER We argue that there is as strong case for full transparency concerning the composition of embryo culture media intended for human use ...

A unique regulatory phase of DNA methylation in the early mammalian embryo
Nature, 2012 DNA methylation is highly dynamic during mammalian embryogenesis. It is broadly accepted that the paternal genome is actively depleted of 5-methylcytosine at fertilization, followed by passive loss that reaches a minimum at the blastocyst stage. However,
