Defects to the sclerotome and subsequent vertebral development were not due to failure of somitogenesis. Taken together, these results suggest that the notochord induced floor plate development before degeneration, and that the remaining floor plate is sufficient for maintenance of differentiation of the somite into the
In birds and mammals, it is well known that the centra originate from the somite-derived sclerotomes, and the molecular basis for sclerotome differentiation is beginning to be .. This raises the intriguing possibility that the notochord has a conserved role in the instruction of vertebral patterning in all vertebrate classes.

24 Jul 2007 The aim of this review is to summarise the current understanding of avian somite and head mesoderm patterning and differentiation, to discuss this in the context of Sclerotomal Pax1 expression is induced by Shh (and Noggin) from the notochord and the floor plate of the neural tube (E, yellow arrow).
found to be required for sclerotome differentiation and proliferation (for a review, see Christ et al., 2000). Despite these insights at the molecular level, the relationship between somite patterning and vertebral segmentation remains to be firmly established. Somites give rise to both axial muscles.
