摘要
Borders are essential for demarcating repeated structures such as somites during vertebrate development. Two recent articles describe roles for Integrin alpha 5 and its ligand Fibronectin1 in zebrafish anterior intersomitic boundary formation and link them to Notch and Eph-Ephrin pathways in epithelialization of somite boundary cells. Together with these pathways, Integrin alpha 5 and Fibronectin1 orchestrate the orderly formation of somite and later myotome borders. These studies shed light on components downstream of the periodic segmentation mechanism - the 'segmentation clock' in somitogenesis.
