Effect of rhEPO on cell loss in the ipsilateral DG at 35 days in both genders after TBI. H & E staining: A-F. Treatment with rhEPO (B, E) reduced cell loss as compared with the saline group (A, D) in both genders. The cell number in the ipsilateral DG is shown in (G). Data represent mean ± SD. * P < 0.05 vs. corresponding Sham. # P < 0.05 between Saline vs. EPO. N (mice/group) = 13 (male-saline), 12 (male-EPO), 8 (male-sham), 8 (female-saline), 8 (female-EPO), 7 (female-sham). Scale bar = 50μm.
