Fig. 2From: Progranulin deficiency exacerbates spinal cord injury by promoting neuroinflammation and cell apoptosis in micePGRN is mainly localized in neuron and activated macrophage/microglia after SCI. Immunofluorescence double staining of spinal tissues from sham and SCI groups with specific antibodies against PGRN (red) or cell markers (green): NeuN (neuron), GFAP (astrocyte), and CD68 (macrophage/microglia). Nuclei were stained by DAPI (blue), and yellow indicates merged image. Bar = 20 μmBack to article page
