In Navarro et al. 2008, figure. 7 was set incorrectly in the published figure (panels SE and EE were transposed). The correct version is inserted below.


Figure 7.  Physiological stimulation of hippocampal neurogenesis in adult rats housed in enriched environment does not require up-regulation of heparanase gene expression. (a) BrdU-incorporating cells were counted in the granule cell layer and subgranular zone of the dentate gyrus of the hippocampal formation in rats sacrificed 10 days after the first of five injections of BrdU (50 mg/kg), as detailed in the method section. Results obtained in rats housed in an enriched environment (EE) are expressed in percent ±SEM of the value measured in rats housed in a standard environment (SE). (b) Expression profile of vascular endothelial growth factor (VEGF) and heparanase transcripts in the hippocampus according to housing conditions. Numbers of cDNA copies are obtained by real time PCR quantification following calibrated RT of mRNAs contained in 500 ng of total RNAs. Results are expressed in percent ± SEM of the value determined in SE rats. ***p < 0.001 (Fisher Least Significance Differences test following one-way anova) as compared to SE rats. Scale bar: a, 50 μm. Abbreviations: HEP, heparanase.
