The Anatomical Record, EarlyView.Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.

Yolk sac utilization in ostrich (Struthio camelus) chicks : research communication
Onderstepoort Journal of Veterinary Research, 2004 The mass of residual yolk sac expressed as a percentage of initial mass of the egg from which the chick hatched decreased sharply in the first 2 days post-hatching.

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.

Electrolyte and Water Balance of the Early Avian Embryo: Effects of Egg Turning [PDF]
, 2002 Formation of sub-embryonic fluid (SEF) is a key aspect of the physiology of the early avian embryo.Here we review the process of SEF formation and the factors which influence its composition and the rate of SEF production and depletion in the Japanese ...

Autism Research, EarlyView.ABSTRACT Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by social communication deficits, repetitive behaviors, and sensory abnormalities. Sodium valproate (VPA) exposure during embryonic development is a well‐established preclinical model for ASD, leading to increased oxidative stress in the developing brain, including ...

Mixed Germ Cell Tumor with Extensive Yolk Sac Tumor Elements in the Frontal Lobe of an Adult
Case Reports in Surgery, 2012 Intracranial nongerminomatous germ cell tumors (NGGCTs) in unusual locations are extremely rare. Here, we report a case of a yolk sac tumor in the frontal lobe in a middle-aged patient.

Egg quality, fatty acids profile, and hatchability of broiler breeders fed diets supplemented with Conjugated Linoleic Acid (CLA) [PDF]
Ciência e AgrotecnologiaConjugated linoleic acid (CLA) refers to a group of positional and geometric isomers of linoleic acid. Hens fed a diet supplemented with CLA exhibit increased levels of saturated fatty acids, which may influence the quality characteristics of eggs and ...

The effect of static incubation on the yolk sac vasculature of the Japanese quail (Coturnix c. japonica) [PDF]
, 2006 Static incubation affects early embryonic development with, notably, a reduction area vasculosa expansion and diminished sub-embryonic fluid (SEF) volume, effects produced during a ‘critical’ period (3-7 days in the chick) (Baggott et al., 2002).

Vascular development and hemodynamic force in the mouse yolk sac
Frontiers in Physiology, 2014 Vascular remodeling of the mouse embryonic yolk sac is a highly dynamic process dependent on multiple genetic signaling pathways as well as biomechanical factors regulating proliferation, differentiation, migration, cell-cell, and cell-matrix ...
