Expression of the Arch-EGFP

Confocal images showing robust expression of Arch-EGFP in Arch-EGFP: Gli1-CreERT2 mice. Mice were injected with tamoxifen on postnatal days 7, 9, 11, 13 and 15 and sacrificed two weeks later. Membranous Arch-EGFP expression was observed in the soma (GCL), axons (Hilus) and apical dendrites (ML) of the DGCs (A). Axonal projections to the startum lucidium of CA3 also expressed Arch-EGFP (B). GCL: Granule Cell Layer, ML: Molecular Layer, CA3: Cornu Ammonis area 3. Scale bar: 50µm.
