Figure Caption
Fig. 2 At the onset of gastrulation the expression of Sef is restricted to the margin. This marginal expression is maintained all along the gastrulation. Expression of Sef is observed in axial hypoblast from the shield stage to the end of gastrulation. Anteriorly Sef is present in posterior prechordal plate but excluded from anterior prechordal plate (presumptive hatching gland territory). After 80% epiboly another expression territory appears in anterior neural plate (presumptive forebrain).
