Figure 2. CB2 receptors control neural progenitor cell proliferation in vivo. A) Number of BrdU-positive cells per section in the dentate gyrus of WT (n=5) and CB2–/– (n=7) mouse E17.5 embryos. B) Number of BrdU-positive cells per section in the dentate gyrus of WT (black bars; n=4) and CB2–/– (gray bars; n=3) adult mice injected with the indicated agents. C) Number of BrdU-positive cells per section in the dentate gyrus of WT (black bars; n=4) and CB2–/– (gray bars; n=4) adult mice injected with saline (plain bars) or kainic acid (dashed bars). Significantly different from controls: *P < 0.05, **P < 0.01. Significantly different from WT mice treated with kainic acid: #P < 0.05.
