WNT6 and cervical squamous intraepithelial neoplasia: Here we present evidence that Wnt6, which is expressed in the same cells as Wg throughout the development of the wing disc in both early and late stages, has no major role in wing fate specification but contributes to driving compensatory proliferation upon tissue damage and to producing tumour-like overgrowths upon CIN induction and additional blockage of the apoptotic pathway (Fig. 8).
