Neurons of the Dbx1 lineage are early born neurons in PC (a) YFP (cells of the Dbx1 lineage, green) and EdU staining (red) in coronal sections from P7 Dbx1^Cre:Ai3 mice. EdU was injected into pregnant mothers at indicated stages. (b–e) Quantification of results from (a), indicating the percentages of EdU⁺/total cells (indicated by DAPI) (b) and EdU⁺YFP⁺/total YFP⁺ cells (d). The numbers and distributions of EdU⁺ cells and EdU⁺YFP⁺ cells at the indicated stages were shown in (c) and (e), respectively (n = 3). Scale bar, 100 µm.
