Stages of embryonic development of the zebrafish
Developmental Dynamics, 1995 We describe a series of stages for development of the embryo of the zebrafish, Danio (Brachydanio) rerio. We define seven broad periods of embryogenesis—the zygote, cleavage, blastula, gastrula, segmentation, pharyngula, and hatching periods.

Bioengineering in vitro models of embryonic development [PDF]
Stem Cell Reports, 2021 Stem cell-based in vitro models of embryonic development have been established over the last decade. Such model systems recapitulate aspects of gametogenesis, early embryonic development, or organogenesis. They enable experimental approaches that have not been possible previously and have the potential to greatly reduce the number of animals required ...

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 ...

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 ...

The Mechanism of Pattern Transitions between Formation and Dispersion [PDF]
Journal of Theoretical Biology. 581, 111736 (2024), 2023 The patterns observed on the body surface of living organisms have traditionally been attributed solely to ecological strategies. However, this study investigates a fascinating phenomenon in Pelodiscus sinensis, where patterns formed on the plastron during embryonic and juvenile stages, which are not externally visible, ultimately disappear in ...

Structure of the mammalian TRPM7, a magnesium channel required during embryonic development
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Ion channels are pore-forming proteins spanning biological membranes. Transient receptor potential ion channels are a subclass of ion channel proteins, characterized by nonselective permeability to cations such as sodium, calcium, magnesium,

Functional roles of hnRNPA2/B1 regulated by METTL3 in mammalian embryonic development
Scientific Reports, 2019 Heterogeneous nuclear ribonucleoprotein A2/B1 (hnRNPA2/B1) plays an important role in RNA processing via in m6A modification of pre-mRNA or pre-miRNA.
