Fig. 4 Expression of snail1 is observed in somites, unsegmented paraxial mesoderm and tail bud. Expression of snail1 disappears from adaxial cells when somites form. and A second territory of snail1 expression appears in the head at the level of head mesoderm that give rise to head mesenchyme. In the unsegmented paraxial mesoderm, snail1 appears more strongly expressed in cells at the level of the presumptive somitic furrow (for the two presumptive somites posterior to the last somitic furrow formed)
