During development, cells become progressively restricted in their lineage choices. The allocation of cells to a specific lineage is regulated by the activities of key signalling pathways and ...

In vivo model systems are essential to study the various roles of this fascinating family of proteins in vertebrates. Among them, the zebrafish offers a number of advantages, for example, rapid ...

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 ...

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 ...

Only two weeks after fertilization, the first sign of the formation of the 3 axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as gastrulation, ...

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 ...

Gastrulation, the process where an embryo reorganizes itself from a hollow sphere into a multilayered structure, is considered a 'black box' of human development. This is because human embryos are ...

During implantation, the human embryo is hidden inside a “black box.” Although peeking inside has been prohibited by the 14-day rule, which restricts in vitro studies to preimplantation events, a new ...
