Figure 6. Reactive microgliosis in the hippocampus of 4-week-old Bmi-1−/− mice.
Compared with WT littermates (A and C), strong immunostaining for the microglial marker Iba-1 was observed in the hippocampus of Bmi-1−/− mice (B and D). Activated microglia with large soma and thick processes (arrowheads) were present at Bmi-1−/− mice (D).
