Characterizing the zebrafish organizer: microsurgical analysis at the early-shield stage [PDF]
, 1996 The appearance of the embryonic shield, a slight thickening at the leading edge of the blastoderm during the formation of the germ ring, is one of the first signs of dorsoventral polarity in the zebrafish embryo.

A comprehensive embryonic staging series of the turtle Trachemys scripta
Developmental Dynamics, EarlyView.Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

Cardiovascular ephrinB2 function is essential for embryonic angiogenesis [PDF]
, 2002 EphrinB2, a transmembrane ligand of EphB receptor tyrosine kinases, is specifically expressed in arteries. In ephrinB2 mutant embryos, there is a complete arrest of angiogenesis.

Developmental Dynamics, EarlyView.Abstract Background CD163 is a scavenger receptor predominantly expressed on the surfaces of macrophages in various mammalian species and is a marker of anti‐inflammatory (M2‐like) macrophages. High density of CD163‐positive tumor‐associated macrophages (TAMs) is associated with worse prognosis in various patient tumors.

Developmental Dynamics, EarlyView.Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Developmental Dynamics, EarlyView.Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.

X-chromosome inactivation mosaicism in the three germ layers and the germ line of the mouse embryo [PDF]
, 1982 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.

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)
Developmental Dynamics, EarlyView.Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Bifunctional Co8FeS8‐FeXCy for oxygen evolution and microwave absorption. Electronic modulation for balancing oxygen intermediates bending energy over oxygen evolution catalytic active sites is one of the most critical factors but still remains challenging.
