Fig. 2From: Tunneling nanotubes evoke pericyte/endothelial communication during normal and tumoral angiogenesisRepresentative confocal microscopy images of blood–brain barrier (BBB)-microvessels and TNTs in the developing human telencephalon at 22 wg. a, c NG2+, pericyte TNTs (arrows) originate from cortex microvessels (V) lined by Glut-1+ BBB-endothelial cells, and pass through a curtain of GFAP+ radial glia fibers; b, d The single channel (red) better shows NG2+ pericytes (PC), which cover the microvessel wall, together with the finer details of their NG2+ TNTs. Nuclear counterstaining SYTOX. Scale bars a, b 25 µm; c, d 20 µmBack to article page
