Interaction of chemokine CXCL12⁺ radial glia with endothelial sprouts and pericyte TNTs. a, b Typical CD105⁺ growing vessels, characterized by tip cells and filopodial processes, appear in extensive contact with CXCL12⁺ radial glia fibers. c, d NG2⁺ forebrain pericyte TNTs are contacted by CXCL12⁺ radial glia fibers. Human telencephalon 22 weeks of gestation. Scale bars a 25 µm; b 10 µm
