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 ...

Somitogenesis is the process by which somites are formed during embryogenesis. Somitomeres are formed first, which are essentially segmented blocks of tissue that differentiate to form the skeletal ...

Researchers used iPS cells to reconstructed the human 'segmentation clock,' a key point in early embryonic development that determines how the body gets segmented. The 'segmentation clock' is a ...

Vertebrates have a pretty diverse array of body plans, and one of the reasons for this is some evolutionary flexibility in the length of their primary body axis, the one that runs from head to tail.

Scientists have investigated lamprey embryos using cutting-edge microscopic techniques to reveal interesting insights about vertebrate head evolution, clarifying an unresolved mystery in basic science ...

New stem cell-based embryo model reveals previously unknown communication between early tissues that become the spine and muscles in the central part of the body. From the moment an embryo starts to ...
