Model of Wnt pathway regulation of egl-18/elt-6 in larval seam cell fate specification. Specification of seam cells in the embryo requires the function of three GATA factor genes: elt-1, egl-18 and elt-6. During the larval asymmetric self-renewal divisions of the seam cells, the Wnt pathway is activated in the posterior daughter to regulate expression of egl-18/elt-6 (and other targets) and maintain the seam cell fate in that daughter cell.
