Abstract
Bone morphogenetic protein 10 (BMP10), is a member of the transforming growth factor β (TGFβ) superfamily. Although BMP10 plays pivotal roles during development, including vascular development and cardiogenesis, little information is available for BMP10 expression in the central nervous system (CNS). We, thus, investigated BMP10 expression in the adult rat CNS using immunohistochemistry. BMP10 was intensely expressed in most neurons and their axons. Furthermore, we found that astrocytes and ependymal cells also express BMP10 protein. These data indicate that BMP10 is widely expressed throughout the adult CNS, and this abundant expression strongly supports the idea that BMP10 also plays important roles in the adult CNS.
