Is osteocrin expressed exclusively in the bone?
['Evolution of Osteocrin as an activity-regulated factor in the primate brain.', 'Here we use transcriptional profiling of human fetal brain cultures to identify an activity-dependent secreted factor, Osteocrin (OSTN), that is induced by membrane depolarization of human but not mouse neurons.', 'Osteocrin (Ostn) is a recently discovered secreted protein produced by cells of the osteoblast lineage that shows a well conserved homology with members of the natriuretic peptide (NP) family. ', 'Osteocrin (Ostn), a bone-active molecule, has been shown in animals to be highly expressed in cells of the osteoblast lineage. ', 'Osteocrin, a novel bone-specific secreted protein that modulates the osteoblast phenotype.']
['No, Osteocrin (Ostn) has been detected in the bones and the brain.']
