NPCs and OPCs differentiated in vitro co-express CXCR4 and its CXCL12 ligand. a, b Representative immunofluorescent images of a NPCs (DCX⁺, green) or b OPC (NG2⁺, green) co-labeled for CXCL12 (red) and CXCR4 (blue). Cells were differentiated from aNSCs cultured in differentiation medium for 6 days. Nuclei were visualized by DAPI counterstaining (white). Scale bar: 20 μm. The panels at the right show individual channels for NPCs or OPC co-stained for CXCR4 (blue) and CXCL12 (red). Scale bar: 20 μm
