Conservation of segmentation
signaling in vertebrates and arthropods
Jun 18, 2003
Segmentation is one of the fundamental mechanisms by which animals develop. In vertebrates, the somites—mesoderm in the vertebrate embryo, occurring in pairs along the notochord that give rise to muscles and vertebrae—develop through successive waves of gene expression known as the segmentation clock. The
Stollewerk et al. observed that, unlike
