Fig. 3From: S100B is selectively expressed by gray matter protoplasmic astrocytes and myelinating oligodendrocytes in the developing CNSS100B is not expressed by neurons. a–c Spinal cord tissues from P4 stage were immunostained simultaneously with S100B and NeuN. Quantitative analysis was showed in (b, c). d–d‴ None of neurons express S100B in different areas of brain tissues. CC corpus callosum. Bar, 100 μmBack to article page
