Pbx deficient mice

Embryos

Using gene targeting techniques, we have created mice that are null for Pbx1.  Their characterization shows that Pbx1 is essential for development.  The phenotypes of Pbx1 null embryos provide compelling support for its in vivo contributions to Hox function during many aspects of embryonic development.  These mice are being used to investigate the roles of Pbx1 in various cellular signaling and growth control pathways.
