Robo signalling controls pancreatic progenitor identity by regulating Tead transcription factors
Nature Communications, 2018 A role for Slit/Robo signalling in pancreas development has not been defined. Here, the authors generate Robo1/Robo2 knockout mice to identify both as needed for establishing initial pancreatic cell identity as well as for proliferation and survival of ...

Epigenetic regulation of germ cell and early embryonic development by Polycomb group proteins [PDF]
, 2011 Mammalian development begins at fertilization, when two highly specialized gametes, sperm and oocyte fuse to form a zygote. It is well established that early development of the embryo is driven by factors that are inherited from the oocyte.

Mechanobiology of Embryonic Limb Development [PDF]
Annals of the New York Academy of Sciences, 2007 Abstract: Considerable evidence exists to support the hypothesis that mechanical forces have an essential role in healthy embryonic skeletal development. Clinical observations and experimental data indicate the importance of muscle contractions for limb development.

Molecular mechanisms separating two axonal pathways during embryonic development of the avian optic tectum [PDF]
, 1991 During embryonic development of the avian optic tectum, retinal and tectobulbar axons form an orthogonal array of nerve processes. Growing axons of both tracts are transiently very closely apposed to each other. Despite this spatial proximity, axons from

Communications Biology, 2022 Ho-Bouldoires, Sollier, Zamfirov and Broders-Bondon et al. show that high frequency pulsatile mechanical stresses maintain the physiological level of mice colon stem cells through the mechanosensitive Ret kinase and that Ret activation is elevated in ...

Signalling Pathways in Embryonic Development [PDF]
, 2018 The formation of a complex multicellular organism from a single cell is one of the most amazing processes of biology. Embryonic development is characterised by the careful regulation of cellular behaviours such that cells proliferate, migrate ...

Developmental potential of aneuploid human embryos cultured beyond implantation
Nature Communications, 2020 Aneuploidy, abnormal chromosome number, is a major cause of early pregnancy loss. Here the authors determine the extent of post-implantation development of human embryos with common aneuploidies in culture, finding developmental arrest of monosomy 21 ...

Nature Communications, 2017 Liver and pancreas cells arise from a common endoderm progenitor in the embryo, but what regulates their cell fate is unclear. Here, the authors show that expression of the Three-Amino-acid-Loop-Extension (TALE) homeobox TG-interacting factor 2 (TGIF2 ...

Regulation of the maternal-to-embryonic transition in "C. elegans" [PDF]
, 2012 Reproduction is a fundamental process of life which allows the survival of each species through the birth of young species members. Several modes of reproduction evolved and are classified into sexual and asexual reproduction.
