Deskripsi
Priming of the adult mouse heart with Tβ4 activates dormant epicardium-derived cells to aid repair of injured myocardium. Here, Vieiraet al. explain this process and show that Tβ4 binds a chromatin remodeller BRG1 and activates Wt1, the key regulator of epicardial epithelial-to-mesenchymal transformation, by altering the epigenetic landscape of the Wt1 locus.
