Cell death and morphogenesis during early mouse development: Are they interconnected? [PDF]
Shortly after implantation the embryonic lineage transforms from a coherent ball of cells into polarized cup shaped epithelium. Recently we elucidated a previously unknown apoptosis‐independent morphogenic event that reorganizes the pluripotent lineage ...

Developmental plasticity, cell fate specification and morphogenesis in the early mouse embryo [PDF]
A critical point in mammalian development is when the early embryo implants into its mother's uterus. This event has historically been difficult to study due to the fact that it occurs within the maternal tissue and therefore is hidden from view. In this

This proof‐of‐concept study involves high‐throughput teratogenicity screening of compounds using XEn/EpiCs, a 3D stem cell‐based embryo model, within microwells. The term ‘morphotoxicity’ is introduced to complement traditional cytotoxicity assays through automated feature extraction and machine‐learning‐assisted classification of morphologies.

Spatial and temporal patterns of distribution of the gap junction protein connexin43 during mouse gastrulation and organogenesis [PDF]
Connexin43 (Cx43) is a member of the family of channel-forming proteins that make up the gap junction and are believed to provide pathways for cell-cell exchange of developmental signals.

Signaling Centers Drive Brachyury Dynamics and Lineage Commitment in mESC Aggregates
We used a mouse embryonic stem cell aggregate model to compare the use of Chiron and BMP4 signaling as pulses (applied to the whole aggregate) or signaling centers (applied to part of the aggregate). BMP4 as a pulse was shown to drive neural differentiation, with Chiron inhibiting this effect.

NF2 is Essential for Human Endoderm Development
This study demonstrates that NF2, moesin‐ezrin‐radixin like (MERLIN) tumor suppressor (NF2) is essential for human endoderm formation. NF2 knockout human induced pluripotent stem cells fail to form endoderm both in vitro and in vivo due to yes‐associated protein 1 (YAP1) nuclear translocation, redirecting differentiation toward myofibroblast‐like cells.

The transcription factor GATA6 is essential for early extraembryonic development [PDF]
The gene coding for the murine transcription factor GATA6 was inactivated by insertion of a beta-galactosidase marker gene. The analysis of heterozygote GATA6/lacZ mice shows two inductions of GATA6 expression early in ...

The study reports that Wnt inhibitors safeguard porcine embryonic stem cells (ESCs) from acquiring the extraembryonic endoderm (XEN) lineage, and further develop an efficient strategy to derive XEN cells from ESCs. The XEN cells from ESCs exhibit similar transcriptome and chromatin accessibility features to XEN cells from embryos and contribute to ...

X-chromosome inactivation mosaicism in the three germ layers and the germ line of the mouse embryo [PDF]
Electrophoretic variant forms of the X-linked enzyme phosphoglycerate kinase (PGK-1, E.C.2, 7, 2, 3) have been used to examine X-chromosome mosaicism in tissues from 121/2-day post coitum heterozygous female mouse embryos.

Digital Three-Dimensional Atlas of Quail Development Using High-Resolution MRI [PDF]
We present an archetypal set of three-dimensional digital atlases of the quail embryo based on microscopic magnetic resonance imaging (µMRI). The atlases are composed of three modules: (1) images of fixed ex ovo quail, ranging in age from embryonic day 5
