Gastrulation is a process common to nearly all metazoan organisms during which an embryo with distinct tissue layers develops out of a seemingly unstructured assembly of cells referred to as 'blastula ...

Researchers offer a phylogenetic and ontogenetic overview of the primitive streak and its role in mediating amniote (vertebrate animals that develop on land) gastrulation, and discuss the implications ...

Gastrulation is the formation of the three principal germ layers - endoderm, mesoderm and ectoderm. Understanding the formation of the basic body plan is not only important to reveal how the ...

Now, a new study reveals that this pivotal step in human development is guided by a precise interplay between chemical signals and physical forces. Published in Cell Stem Cell, the paper introduces a ...

When the zygote, or the fertilised egg, starts to develop, the soon forming inner cell mass, a cluster of cells that will eventually develop into the individual, retains its pluripotent stem cell ...

An unexpected link has been found between the metabolic pathways that produce energy for embryo growth, and the cellular signalling systems that regulate cell specialization and movement during early ...

This is a preview. Log in through your library . Abstract Three lines of evidence are presented to support the concept that polyingression represents a major morphogenetic movement in the genesis of ...

How are the body’s segments formed? The body of a vertebrate organism consists of segmented axes, which is most distinct in the skeleton. The process of somitogenesis is key to the development of ...

Gastrulation is the formation of the three principal germ layers - endoderm, mesoderm and ectoderm. Understanding the formation of the basic body plan is not only important to reveal how the ...

In their publication in Science, Professor Guojun Sheng (Kumamoto University, Japan), Professor Alfonso Martinez Arias (Universidad Pompeu Fabra, Spain) and Professor Ann Sutherland (University of ...

Scientists revise the current textbook knowledge about gastrulation, the formation of the basic body plan during embryonic development. Their study in mice has implications for cell replacement ...
