Detailed transparent video showing notochord cells (red) and the associated patterning molecules (in cyan) inside a trunk organoid. Cell nuclei in gray. Electron scanning microscopy image (2 ...

This paper describes how the vertebrate version of the hedgehog gene-as expressed by the notochord (an embryonic structure)-induces the formation of floor plate cells and motor neurons in the ...

For the first time, scientists at the Francis Crick Institute have successfully developed human stem cell models that include a functional notochord—a crucial tissue in embryonic development ...

Many four-legged animals go through embryonic stages that have similar features -- gill arches, a notochord, segmentation, and paddle-like limb buds -- as they develop into different adults.

While the lab-grown tissues replicate many features of natural notochord development, they don’t perfectly match embryonic tissues. The structures are smaller and simpler than those in real embryos.
