The yolk sac is an embryonic membrane that is essential for the embryo's initial survival in many mammals. It also plays an important role in the production of proteins necessary for development. We studied proteins of the ...

Background: The bovine yolk sac derives from visceral endoderm and its development occurs between days 18-23 of gestation. The study of this membrane is important for comparative data and has already been performed in ...

Few reports are available concerning yolk sac remnants in the equine species, with little information on histopathological findings. A stillborn mini-pony foal showed a fluid-filled mass, measuring about 10 cm in circumference, ...

Caviomorph development includes an inverted yolk sac. Since principle processes are not understood, we investigated its differentiation in Galen and re-examined material from the guinea pig. Galea showed the typical ...

Effects of yolk sac removal (deutectomy) upon performance of chicks from three divergent strains were tested to evaluate the importance of endogenous nutrition on the post-hatch phase. Chicks from three different strains ...
