title: Rat fibroblast growth factor receptor-4 mRNA in the brain is preferentially expressed in cholinergic neurons in the medial habenular nucleus.
abstract: We examined the cellular localization of fibroblast growth factor receptor (FGFR)-4 mRNA preferentially expressed in the medial habenular nucleus by in situ hybridization. FGFR-4 mRNA was expressed in the ventral part of the medial habenular nucleus. FGFR-4 mRNA was colocalized with choline acetyltransferase mRNA to a high degree (more than 90%), indicating that FGFR-4 mRNA-expressed cells are cholinergic neurons. The present finding indicates that FGFR-4 in the brain has a function specific to cholinergic neurons in the ventral part of the medial habenular nucleus.
