YAP/TAZ activity in PDGFRα-expressing alveolar fibroblasts modulates AT2 proliferation through Wnt4
Song et al. show that YAP/TAZ signaling in PDGFRα-expressing fibroblasts plays a crucial role in supporting alveolar epithelial stem cells. Their study shows that fibroblast-specific knockdown of YAP/TAZ enhances the ability of PDGFRα+ fibroblasts to support AT2 cell proliferation via Wnt4, highlighting potential pathways for improving lung repair and regeneration.
