Abstract Wnt proteins are a family of molecules that help control how cells grow, develop and communicate – processes that are fundamental to the development and health of all animals. Although Wnt pathways have been studied extensively in model species, very little is known about how they operate in marine fish.

Zebrafish embryonic explants undergo genetically encoded self-assembly
Embryonic stem cell cultures are thought to self-organize into embryoid bodies, able to undergo symmetry-breaking, germ layer specification and even morphogenesis.

Cell Division Drives Epithelial Cell Rearrangements during Gastrulation in Chick
Summary During early embryonic development, cells are organized as cohesive epithelial sheets that are continuously growing and remodeled without losing their integrity, giving rise to a wide array of tissue shapes.

Abstract Understanding the factors that shape population genetic structure is crucial for advancing evolutionary studies and developing effective management and conservation strategies. The northern pike (Esox lucius L.) is a top teleost predator that inhabits fresh and brackish water environments in the northern hemisphere.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Cell proliferation has generally been considered dispensable for anteroposterior extension of embryonic axis during vertebrate gastrulation. Signal transducer and activator of transcription 3 (Stat3), a conserved controller of cell proliferation ...

ABSTRACT The aim of this study was to provide an initial description of the embryology and larval development of Balistes capriscus species obtained from natural spawning in captivity. The study also aimed to assess the stocking density and the impact of offering four types of live food as the initial feed during the larviculture phase. Observations of

Understanding the coordination of the forces generated in embryos by two processes, convergent extension and convergent thickening, is key to understanding how a hollow sphere of cells develops into an elongated embryo.

Regulation of gastrulation movements by emergent cell and tissue interactions
It is during gastrulation that the primordial germ layers are specified, embryonic axes become morphologically manifest, and the embryonic body plan begins to take shape.

ABSTRACT FOXA2 (hepatocyte nuclear factor‐3β, HNF‐3β) encodes a transcriptional activator involved in early embryogenesis, particularly in the patterning and differentiation of midline structures such as the neural tube, foregut, and pituitary gland. Its role in human pathogenesis was first suspected when patients with deletion of chromosome 20p11.2 ...
