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.

Distribution of O-Acetylated Sialic Acids among Target Host Tissues for Influenza Virus. [PDF]

, 2017
Sialic acids (Sias) are important glycans displayed on the cells and tissues of many different animals and are frequent targets for binding and modification by pathogens, including influenza viruses.

Laboratory Biology, Immature and Adult Morphology of Trichopria drosophilae (Perkins) (Hymenoptera: Diapriidae), Parasitoids of Drosophila Flies

Entomologia Experimentalis et Applicata, EarlyView.
This study investigates the laboratory biology and morphology of the parasitoid Trichopria drosophilae, which targets Drosophila flies, including the invasive Drosophila suzukii. Key findings include a detailed description of the parasitoid's egg, three larval instars, and pupal stage, as well as unique behaviors such as siblicide and encapsulation in ...

Extraembryonic membrane morphology in greater rheas (Rhea americana americana Linnaeus, 1758)

Zoomorphology, 2023
The greater rhea, Rhea americana, is a wild ratite of high scientific importance and significant and zootechnical value, especially considering the current development state of Brazilian poultry production, where research aimed at increasing the productivity of these animals has become extremely relevant.

Pathways of trunk neural crest cell migration in the mouse embryo as revealed by vital dye labelling [PDF]

, 1990
Analysis of neural crest cell migration in the mouse has been difficult due to the lack of reliable cell markers. Recently, we found that injection of DiI into the chick neural tube marks premigratory neural crest cells whose endfeet are in contact with ...

Monoamine oxidase A expression is vital for embryonic brain development by modulating developmental apoptosis [PDF]

, 2011
Monoamine oxidases (MAO-A, MAO-B) metabolize biogenic amines and have been implicated in neuronal apoptosis. Although apoptosis is an important process in embryo development, the role of MAO isoenzymes has not been investigated in detail.

Liver X Receptor α (LXRα) Regulates 5β‐Reductase (AKR1D1) Expression in Avian Embryos: Implications for Yolk Steroid Metabolism

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 5, Page 456-461, June 2026.
ABSTRACT Steroid‐mediated maternal effects are well‐studied as a source of phenotypic variation. In bird eggs, the yolk contains various steroids that can influence embryonic development. However, one complicating factor in understanding how yolk steroids affect development is that the embryo metabolizes yolk steroids to regulate exposure.

Sexual Antagonism and the Evolution of X Chromosome Inactivation [PDF]

, 2013
In most female mammals, one of the two X chromosomes is inactivated early in embryogenesis. Expression of most genes on this chromosome is shut down, and the inactive state is maintained throughout life in all somatic cells.

An Engineered Living Material With Pro‐Angiogenic Activity Inducible by Near‐Infrared Light

Advanced Functional Materials, Volume 36, Issue 40, 18 May 2026.
NIR‐responsive engineered living materials (ELMs) for controlled angiogenesis: Near‐infrared (800 nm) light activates engineered probiotic bacteria within alginate‐based living materials to secrete a blood vessel‐regenerating protein. The released protein promotes pro‐angiogenic effects in endothelial networks and chick chorioallantoic membranes.

Spatiotemporal segmentation of contraction waves in the extra-embryonic membranes of the red flour beetle

BMC Bioinformatics
Background In this paper, we introduce an image analysis approach for spatiotemporal segmentation, quantification, and visualization of movement or contraction patterns in 2D+t and 3D+t microscopy recordings of biological tissues. The development of this
