Effects of repeated treatment with rolipram, piclamilast, or CDP840 on cell proliferation and survival in rat hippocampus. Treatment for 16 days with rolipram or piclamilast increased cell proliferation (A) and survival (B). CDP840 treatment increased proliferation (A) but not survival (B). Bars represent means ± S.E.M. (n = 3–4 per group). **, P < 0.01; *, P < 0.05 versus corresponding control.
