In vivo expression of Osterix in mature granule cells of adult mouse olfactory bulb

► Osterix is expressed in the mouse olfactory bulb as well as bone. ► Osx-expressing cells exist in the mature interneuron region of the granule cell layer of the adult mouse olfactory bulb. ► The Osx-expression in mature interneurons may suggest that Osx is a new marker for mature neuroblasts.
