Distribution of eGFP+ cells along the rostro-caudal axis. Chimera mice with bone marrow constitutively expressing eGFP received brain irradiation (0 or 45 Gy) and were sacrificed at 6 months post-radiation. a Sections taken 1:24 were stained with Hoechst solution, and photomicrographs of the striatum and internal capsule for both control and irradiated mice were taken. Scale bars: 100 μm. b The number of eGFP+ cells per square millimeter was plotted in relation to the estimated distance from bregma (mm) in 0- and 45-Gy brain-irradiated animals. c The number of eGFP+ cells per square millimeter in 45-Gy brain-irradiated chimera mice was plotted in relation to the section containing the peak infiltrate of eGFP+ cells
