Zebrafish embryonic explants undergo genetically encoded self-assembly
eLife, 2020 Embryonic stem cell cultures are thought to self-organize into embryoid bodies, able to undergo symmetry-breaking, germ layer specification and even morphogenesis.

Epiblast morphogenesis before gastrulation
Developmental Biology, 2015 The epiblast is a single cell-layered epithelium which generates through gastrulation all tissues in an amniote embryo proper. Specification of the epiblast as a cell lineage in early development is coupled with that of the trophoblast and hypoblast, two lineages dedicated to forming extramebryonic tissues.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.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 ...

Spatial and temporal patterns of distribution of the gap junction protein connexin43 during mouse gastrulation and organogenesis [PDF]
, 1992 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.

Evolutionary plasticity of developmental gene regulatory network architecture [PDF]
, 2007 Sea stars and sea urchins evolved from a last common ancestor that lived at the end of the Cambrian, approximately half a billion years ago. In a previous comparative study of the gene regulatory networks (GRNs) that embody the genomic program for ...

The X Factor in Immunity: Sex Differences Shaped by the X Chromosome
Immunological Reviews, Volume 338, Issue 1, March 2026.ABSTRACT There are sex differences with immune responses where females exhibit stronger immune responses compared to males. Both sex hormones and sex chromosome differences between males and females contribute to the observed sex differences with innate and adaptive immune cell composition and function.

Macromere cell fates during sea urchin development [PDF]
, 1991 This paper examines the cell lineage relationships and cell fates in embryos of the sea urchin Strongylocentrotus purpuratus leading to the various cell types derived from the definitive vegetal plate territory or the veg_2 tier of cells.

Timing of NAD Deficiency During Organogenesis Dictates Defect Type and Penetrance
The FASEB Journal, Volume 40, Issue 3, 15 February 2026.Pregnant mice on a vitamin B3‐free and tryptophan‐limited diet have embryos with Congenital NAD Deficiency Disorder, characterized by malformations and/or death. We longitudinally tracked the maternal NAD metabolome, embryo growth, and malformation occurrence. Mice with lower NAD Salvage Pathway metabolite levels and minimal levels of derived excretion

Neurogenesis and the Epigenetic Landscape: Role of Histone Modifications and Chromatin Remodeling
Brain and Behavior, Volume 16, Issue 2, February 2026.Histone methylation and acetylation modulate gene expression by inducing chromatin condensation or relaxation, which in turn regulates transcriptional activity and impacts neurogenesis. ABSTRACT Aims The purpose of this review is to examine how epigenetic regulation particularly chromatin modification and histone methylation controls gene expression ...
