Site-Specific Distribution of CD68-Positive Microglial Cells in the Brains of Human Midterm Fetuses: A Topographical Relationship with Growing Axons

Figure 1

Distribution of CD68-positive microglial cells in and around the internal capsule at 15 weeks. Panel (a) immunohistochemistry of vimentin, and panel (b) immunohistochemistry of CD68 display near sections. Microglial cell accumulation in the corona radiata is clearly seen in the anterosuperior aspect of the putamen (stars in panel (b)). Insert at the bottom of panel (b) is a negative control showing the corona radiata. Panel (c) exhibits CD68-posiitve cells in the choroid plexus. Panels (d), (e), and (f), corresponding to squares in panel (b), display higher magnification views of CD68-positive microglial cells.
