Site-Specific Distribution of CD68-Positive Microglial Cells in the Brains of Human Midterm Fetuses: A Topographical Relationship with Growing Axons
Figure 3
Distribution of CD68-positive microglial cells in a brain at 25 weeks. Panels (a) and (c) are immunohistochemistry of glial fibrillary acidic protein, while panels (b) and (d) are that of CD68. Panels (a) and (b) (near sections) display the corona radiata in the anterosuperior side of the putamen: CD68-positive cells are seen along nerve fiber bundles (bundled by semicircles). Panels (c) and (d) (near sections) exhibit the optic tract: CD68-positive cells are accumulated in the posteroinferior side of the tract. Arrowheads in panels (a) and (d) indicate vessels containing no cells. Insert in panels (b) and (d) shows the higher magnification of microglial cells.
