Fig. 4From: S100B is selectively expressed by gray matter protoplasmic astrocytes and myelinating oligodendrocytes in the developing CNSS100B is expressed in gray matter astrocytes but not white matter GFAP+ astrocytes. a–i Double labeling of S100B with ALDH1L1 and GFAP in the cortical region (a, c, e, h) and corpus callosum (b, d, f, g, i) of forebrain from P4 to adulthood. j–l Double labeling of S100B with ALDH1L1, GS and GFAP in P4 spinal cord. The arrow heads indicate the S100B+ astrocytes, and S100B+ cells that did not express astrocyte marker are indicated by white arrows. m, n Quantitative analysis of S100B expression in astrocytes. sc spinal cord, WM white matter, GM gray matter, CC corpus callosum. n = 3, *p < 0.05, **p < 0.01.
