Figure 2. Kinetics of radiation-induced alterations in the cellular composition of the DG after irradiation at 10D and 10W.

A–B. and K–L. Immunostaining and quantification for GFAP, C–D. and H–N. PCNA, E–F. and O–P. Sox2 and G–H. and Q–R. Dcx at 1 and 7 days, and at 1 and 6 months after irradiation at 10D and 10W. I–J. and S–T. Immunostaining and quantification for NeuN at 1 and 6 months after irradiation at 10D and 10W. Images, 10x magnification, scale bar = 100 μm; high magnification 100x scale bar = 10 μm. Data are reported as mean ± SEM *P < 0.05; **P < 0.01; ***P < 0.0001 for comparison with controls (Student-t test unpaired). The number of animals used is n = 4–5.
