G Representative pictures of immunostainings against cell type-specific proteins (all depicted in white). Recombined cells were identified by GFP, rNSCs by their radial process labelled with NESTIN (P3, P7) or GFAP (P10, P14), astrocytes by ACSBG1, immature neurons expressed DCX, and proliferating cells the cell cycle markers KI67 (P3, P7) or MCM2 (P10, P14). H Quantification of the percentages of GFP+ recombined cell types out of all recombined cells at distinct timepoints. Intermediate precursor cells (IPCs) identified by TBR2 expression were added to DCX+ neuroblasts. I Quantification of the proportions of proliferating cell types (rNSCs, IPCs/neuroblasts, astrocytes) out of all proliferating cells at P3, P7, P10, P14. Data information: Values represent mean ± SEM; number of experimental animals: (H,I) n = 5 (P3), = 6 (P7, P10, P14); dotted lines label GZ borders; scale bars = 50 µm.
