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 ...

Researchers led by Kyoto University have reconstituted the human 'segmentation clock' -- a key focus of embryonic development research -- using induced pluripotent stem cells, iPSCs. From the first ...

Figure 1: A fluorescence image of an induced presomitic mesoderm (iPSM) tissue model, where cells expressing the Hes7 gene—a key regulator of somite formation—are labeled green. Purple cells express a ...

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 ...

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.

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 ...
