Masatake Kai and Professor Makoto Kondo focused on this paraxial protocadherin (PAPC), which is excluded when dividing cells migrate and form the notochord in the embryo. The findings were ...

Scientists have officially grown a notochord—the tissues that act as the “GPS for the developing embryo” by guiding the formation of the spine and nervous system. Previous attempts to create ...

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 ...

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.

When Schwann heard about the nucleus, he realized that he had seen a similar structure in the vertebrate notochord—a rodlike structure in the embryo that develops into the spinal column. Sure enough, ...
