WebMar 22, 2016 · A major early notochord function is production of Shh, which signals to the somites to sustain cell survival and induce ventral sclerotome fate (vertebral progenitors) ( 1, 2 ). The loss of vertebrae caused by marked apoptosis in somites in T-knockdown embryos is highly reminiscent of the Shh−/− phenotype in axial skeleton ( 2 ). WebJul 1, 1996 · Using fate mapping techniques, we have analyzed development of cells of the dorsal marginal region in wild-type and mutant zebrafish. We define a domain in the early gastrula that is located just at the margin and centered on the dorsal midline, in which most cells generate clones that develop exclusively as notochord.
