Bone morphogenetic protein 9 (BMP9), also known as growth differentiation factor 2 (GDF2), is a member of the transforming growth factor β (TGF β) superfamily. Although BMP9 plays pivotal roles during development, including angiogenesis, hematopoiesis, hepatogenesis, osteogenesis, and glucose metabolism, little information is available for BMP9 expression in the central nervous system (CNS). We, thus, investigated BMP9 expression in the adult rat CNS using immunohistochemistry. BMP9 was intensely expressed in most neurons and their axons. Furthermore, we found that oligodendrocytes and ependymal cells also express BMP9 protein. These data indicate that BMP9 is widely expressed throughout the adult CNS, and this abundant expression strongly supports the idea that BMP9 also plays important roles in the adult brain.
