Fig. 2. snail1b knockdown does not affect mesodermal fate. (A-D) The axial and paraxial mesoderm form normally in snail1b morphants at tail bud stages (tb), as observed by the expression of ntl and paraxial protocadherin (papc), respectively. (E,F) MyoD expression at the 18-somite stage shows that knockdown of snail1b does not prevent the formation of somites.
