Table 1. Phenotype of BrdU+ Cells in the Dentate Gyrus.

Mice in each group received 5 daily injections (150 mg/kg per day) of BrdU and were sacrificed 21 days later. Percentages of BrdU+ cells double labeled for NeuN (mature neurons), GFAP (mature astrocytes), or neither (Other) were analyzed (n = 5 per group). Data are presented as group means (± SEM).

	% NeuN+	%GFAP+	%Other
Sham	45.64 (6.97)	21.24 (3.39)	33.11 (7.71)
Sham-Run	64.00 (2.56)*	14.97 (2.88)	21.03 (4.22)
IRR	20.33 (3.22)*	22.24 (4.51)	57.43 (5.81)*
IRR-Run	41.60 (2.73)**	14.34 (5.04)	44.05 (2.77)
