Localization of BDNF in the spinal cord after hind-paw incision. Representative photomicrographs of the double immunofluorescence of BDNF (red, Figure 2A) with NeuN-IR (marker of neuron, green in Figure 2B), GFAP-IR (marker of astrocyte, green in Figure 2C) or OX-42 (marker of microglia, green in Figure 2D). Note that abundant BDNF expressing cells were also expressed in the neurons but scarcely expressed in the astrocytes or microglia. Bar = 150 μm.
