EMT endows cells with migratory, and sometimes invasive, capabilities and is thus a key process in embryo morphogenesis and cancer progression. So far, Matrix Metalloproteinases (MMPs) have not been considered as key players in EMT but rather studied for their role in matrix remodelling in later events such as cell migration per se. Here we used Xenopus neural crest cells to assess the role of MMP28 in EMT and migration in vivo. We provide strong evidence indicating that MMP28 produced by neighbouring placode cells is imported in the nucleus of neural crest cells for EMT and migration to occur.Competing Interest StatementThe authors have declared no competing interest.
