Ectopic expression of Xnr4 can induce and dorsalize mesoderm. These studies suggest that Xnr4, along with other nodal-related genes (Xnr1-3), may participate in mesodermal patterning and possibly neural development."]},"AuthorList":{"@attributes":{"CompleteYN":"Y"},"Author":[{"@attributes":{"ValidYN":"Y"},"LastName":"Joseph","ForeName":"E
