In the earliest stage of life, animals undergo some of their most spectacular physical transformations. Once merely blobs of dividing cells, they begin to rearrange themselves into their more ...

The architecture of the body is not encoded as a formal blueprint; rather, it's the tightly orchestrated activation and ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

Small fold – big role: A tissue fold known as the cephalic furrow, an evolutionary novelty that forms between the head and the trunk of fly embryos, plays a mechanical role in stabilizing embryonic ...

Building tissues and organs is one of the most complex and important tasks that cells must accomplish during embryogenesis. Individual cells do not make these decisions; rather, building tissue is a ...

In order to survive, organisms must control the pressure inside them, from the single-cell level to tissues and organs. Measuring these pressures in living cells and tissues in physiological ...

In the earliest stage of life, animals undergo some of their most spectacular physical transformations. Once merely blobs of dividing cells, they begin to rearrange themselves into their more ...

Microscopy image of a PGA at day 8 showing the early tissues supporting the embryo, including the amniotic sac and the yolk sac-like structures, surrounded by (extra-embryonic) mesoderm tissue.

Evolutionary response to mechanical stress The increased mechanical instability caused by embryonic tissue movements may have contributed to the origin and evolution of the cephalic furrow genetic ...
