Figure 2.

The distribution of β-galactosidase positive cells in brains of mice at 3 or 15 wk after injection of rAAV2βgal, rAAV4βgal, or rAAV5βgal. β-galactosidase-positive cells within the ependymal, striatal, or “other” (septal and fornix regions, corpus callosum, and neocortex) regions, from sections encompassing the injection site, were counted and that value represented as a percent of the total number of transgene positive cells. (A) Data from sections obtained 3 or 15 wk after intraventricular injection. (B) Data from sections obtained 3 or 15 wk after injection into the striatum. Data represent means ± SEM.
