The Wnt/?-catenin pathway plays a central role in epidermal homeostasis and regeneration, but how it affects fibroblast fate decisions is unknown. We investigated the effect of targeted ?-catenin stabilization in dermal fibroblasts. Comparative gene expression profiling of stem cell antigen 1- (Sca1-) and Sca1+ neonatal fibroblasts from upper and lower dermis, respectively, confirmed that Sca1+ cells had a preadipocyte signature and showed differential expression of Wnt/?-catenin?associated genes. By targeting all fibroblasts or selectively targeting Dlk1+ lower dermal fibroblasts, we found that ?-catenin stabilization between developmental stages E16.5 and P2 resulted in a reduction in the dermal adipocyte layer with a corresponding increase in dermal fibrosis and an altered hair cycle. The fibrotic phenotype correlated with a reduction in the potential of Sca1+ fibroblasts to undergo adipogenic differentiation ex vivo. Our findings indicate that Wnt/?-catenin signaling controls adipogenic cell fate within the lower dermis, which potentially contributes to the pathogenesis of fibrotic skin diseases.
