title: Dorsal root ganglion regulates the transient ERK activation in the dorsal horn of the spinal cord during development.
abstract: In the dorsal horn of the chick embryo spinal cord, extracellular signal-regulated kinase (ERK) was phosphorylated transiently during embryonic days 6 and 9. Co-culture studies suggested that dorsal root ganglion (DRG) activated ERK in the dorsal horn. Brain-derived neurotrophic factor (BDNF) activated ERK in the dorsal horn, and anti-BDNF blocked the DRG-induced ERK activation. These results suggest roles of BDNF in the DRG-induced ERK activation in the embryonic dorsal horn.
