Dentate gyrus (DG) development in the mouse from E10 to postnatal stage. (A) The migration and differentiation of granule cells is controlled by the CH, a glial scaffold formed by radial glial cells (RGCs) and CR lining the HF. At E10–E12.5 DG precursor cells (small dark blue) start to develop in the DNE, adjacent to CH (light blue). (B) By E14–E15.5 the first migration of DG precursors is initiated. (C) By E17.5 DG precursors and granule cells have begun to mix and form the 2ndM and 3ndM. (D) By P0 condensing of granule cell layers (GCLs) in subgranular zone.
