Description : The functional properties of biomineralized structures found in Nature result from interactions between their hybrid components – both organic (mostly proteins) and inorganic (mineral) phases – to generate hierarchical organization across different length scales.  In its dual function, the calcitic ...

Description : The avian eggshell is a thin mineral layer (350 µm thick in chicken) that protects the egg content against mechanical impacts, dehydration and microorganism contamination. Eggshell formation is a highly controlled and rapid mineralization process occurring while the egg is residing in the uterus ...

Description : Egg morphology is essential for animal survival, mediating the interactions between embryos and their environment, and a result have evolved into an enormous diversity of forms and functions in modern vertebrates. Reptiles show considerable variation in the degree eggshell calcification, which through ...

Canal-U
Description : Avian eggs possess very efficient and orchestrated systems to protect the embryo during incubation, until hatch. Although the internal components of the egg are assumed to be sterile, the surface of the eggshell is covered by microbes (essentially bacteria) that may contribute to prevent eggshell ...

Description : Avian eggs have a proteinaceous cuticle covering the outside of the eggshell forming a barrier to the transmission of microorganisms. Although the cuticle is similar to the organic matrix, its secretion is separate from the organic matrix and occurs just prior to oviposition. Using NGS sequence ...

Description : The avian egg is designed to support the autonomous development of the chick embryo in the outside environment. It initially contains all the nutrients required for embryonic growth and provides efficient physical and immune protections primarily via the calcified eggshell and the numerous antim ...
