The primitive streak is a structure that marks the beginning of gastrulation and lays the foundation for the three primary layers of the embryo. One of those layers, the mesoderm, forms during ...

During the tightly regulated gastrulation, embryonic cells differentiate into the three germ layers – endoderm, mesoderm, and ectoderm – which eventually give rise to all tissues and organs.

Known as gastrulation, this crucial process unfolds in the third week of human development. “Gastrulation is the origin of our own individualization, the emergence of our axis,” says ...

Gastrulation is the key event in an embryo’s development when a mass of undifferentiated cells begin the first steps of a long journey in the womb towards formation of a human being.

Around the 14th day of embryonic development, a key stage in human growth called gastrulation kicks off. Cells begin to organize into layers that form the early buds of organs.

The EMT the researchers were studying happens early in an embryo’s development during a process called gastrulation — that’s when cells originating in an epithelial layer break away and move around ...

A synthetic embryo can now be constructed from very early pre-embryonic cells – without the need for an egg or sperm. These were initially created in mice. In April, Chinese researchers created ...
