The formation and maintenance of boundaries between neighbouring groups of embryonic cells is vital for development because groups of cells with distinct functions must often be kept physically separated. Furthermore, because cells at the boundary often take on important signalling functions by acting as organizing centres, boundary shape and integrity can also control the outcome of many downstream patterning events. Recent experimental findings and theoretical descriptions have shed new light…

Signals and mechanics shaping compartment boundaries in Drosophila
TLDR
Key to the separation of compartments is a local increase of actomyosin‐dependent mechanical tension at cell junctions along the boundary, which acts as a barrier to cell mixing during cell division and influences cell rearrangements during cell intercalations along the compartment boundary in a way that the straight shape of the boundary is maintained.
Physical Mechanisms Shaping the Drosophila Dorsoventral Compartment Boundary
Hydra, a model system to trace the emergence of boundaries in developing eumetazoans.
TLDR
Hydra, a representative of the basally branching metazoan Cnidaria, is an interesting prebilaterian model system to study the emergence of boundary-forming mechanisms during evolution.
Boundary formation in the development of the vertebrate hindbrain
TLDR
Studies of vertebrate hindbrain development have given important insights into mechanisms that underlie the formation and maintenance of sharp borders, including the regulation of cell adhesion and contact inhibition of cell migration.
Cellular Mechanisms of Embryonic Tissue Organization
TLDR
It is shown that new junctions elongate in pulses anti-correlated with the periodic contractions of the cells anterior and posterior to the new contact, and applying ectopic tension orthogonal to the characteristic orientation of vertex resolution is sufficient to slow down new edge elongation.

Quantitative approaches in developmental biology
TLDR
It is described how mathematical modelling has become an invaluable method to integrate quantitative biological information across temporal and spatial scales, serving to connect the activity of regulatory molecules with the morphological development of organisms.
Cell surface mechanics and the control of cell shape, tissue patterns and morphogenesis
TLDR
A range of developmental phenomena can be explained by the regulation of cell surface tension, and the framework that emerges from diverse disciplines such as cell biology, physics and developmental biology points to adhesion and cortical actin networks as regulators ofcell surface mechanics.
Compartments and their boundaries in vertebrate brain development
TLDR
The results of recent studies have clarified where compartment boundaries exist, shed light on molecular mechanisms that underlie their formation and have revealed an important function of these boundaries: the positioning and stabilization of local signalling centres.

TLDR
It is found that the boudary regions of the chick embryo hindbrain contain enlarged extracellular spaces and that these form conduits for axons subsequently extending in the circumferential plane of the hindbrain.
An actomyosin-based barrier inhibits cell mixing at compartmental boundaries in Drosophila embryos
TLDR
It is shown that cells can transiently invade neighbouring compartments, especially when they divide, but are then pushed back into their compartment of origin, and proposed that local regulation of actomyosin contractibility, rather than differential adhesion, is the primary mechanism sorting cells at compartmental boundaries.
Dynamic 3D Cell Rearrangements Guided by a Fibronectin Matrix Underlie Somitogenesis
TLDR
This is the first 4D in vivo recording of a full mesenchyme-to-epithelium transition of cells from the presomitic mesoderm and highlighted the importance of the extracellular matrix as a guiding cue during morphogenesis.
Morphological boundary forms by a novel inductive event mediated by Lunatic fringe and Notch during somitic segmentation.
TLDR
It is suggested that the boundary-forming signals emanating from the posterior border cells are mediated by Notch, the action of which is confined to the border region by Lunatic fringe within the area where mRNAs of Notch and its ligand are broadly expressed in the presomitic mesoderm.
Nature and anisotropy of cortical forces orienting Drosophila tissue morphogenesis
TLDR
It is shown that anisotropy of cortical tension at apical cell junctions is sufficient to drive tissue elongation in Drosophila melanogaster embryos, and the contribution of subcellular tensile activity polarizing junction remodelling and the permissive role of vertex fluctuations during tissues elongation is delineated.
