Dextran does not deposit at needle insertion. a Representative frontal brain section of a mouse intrathecally injected with fluoresceinated dextran (40,000 MW) 1 day post sterile needle insertion. The section was co-stained anti-GFAP (red). Dextran was not observed in and around the needle track. b and c show higher magnification of the contralateral and ipsilateral hemispheres, respectively. GFAP staining (red) was used to identify the needle track (white arrow). Bar 100 μm
