DMS promotes neural progenitors proliferation in rodents. (A) Hippocampal DG Ki67 immunostaining on mice with continuous DMS with Program 5 treatment for 7 days. Blue: DAPI; Green: Ki67 staining. Right panel: Amplification of boxed area of left panel. Scale bar = 100 μm. (B) Quantification of (A). (C) Hippocampal DG BrdU immunostaining on 9 month old mice with continuous DMS with Program 1 or 5 treatment. (D) Quantification of (C). Values represent mean (±) SEM (Animal amounts: Control n = 4, P1 n = 3, P5 n = 4; *: P < 0.05, two-tailed student’s t-test). Scale bar = 50 μm.
