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 ...

A collaboration of researchers from Japan, Spain and the U.S. offers a phylogenetic and ontogenetic overview of the primitive streak and its role in mediating amniote (vertebrate animals that develop ...

Scientists have been able to get a rare glimpse into a crucial, early stage of human development by analyzing an embryo in its third week after fertilization — a moment in time that has been difficult ...

With the construction of a building, one of the first steps before creating the upright structure is to set the foundations and the floorplan. Mammalian development is not so different. A ...

Scientists from Helmholtz Zentrum München revise the current textbook knowledge about gastrulation, the formation of the basic body plan during embryonic development. Their study in mice has ...

Molecular and cellular mechanisms of epithelial–mesenchymal transition (EMT), crucial in development and pathogenesis, are still poorly understood. Here we provide evidence that distinct cellular ...

It’s one of life’s most defining moments—that crucial step in embryonic development, when an indistinct ball of cells rearranges itself into the orderly three-layered structure that sets the stage for ...

Materials scientists at UNSW Sydney have shown that human pluripotent stem cells in a lab can initiate a process resembling the gastrulation phase – where cells begin differentiating into new cell ...

Uniting three different parameters in single cells taken from mouse embryos reveals more about how foundational cell identities are established in early development The first single-cell multi-omics ...
