Regulating mirror symmetry in vulval precursor cells (VPCs left) and a hypothetical model regulating the somatic gonadal precursors (SGPs right). A centrally localized Wnt cue reorients the posterior VPC while a hypothesized Wnt antagonist locally depletes the central somatic gonad of Wnt to provide a central proximal-distal axis that promotes mirror asymmetry across a tissue. Asterisks denote ACDs with refined polarity compared to the global ground polarity orienting most ACDs toward the posterior. SFRP, secreted Frizzled-related protein. Color scheme as in Figure 1.
