Histological analysis of neural stem cell (NSC) graft survival and endogenous glial cell responses. First row, NSC-Luciferase/enhanced fluorescent green protein (Luc/eGFP) graft survival. Direct eGFP fluorescence (green) combined with TOPRO3 staining (false colour representation in blue) at day 0, 1, 3, 5, 7 and 14 post-implantation. Representative images were chosen from multiple stained slides (n = 6 to 9 for eGFP/TOPRO3 combination) per mouse analysed at each time point. The provided scale bars indicate 200 μm. Second row, cellular hypoxia. Direct eGFP fluorescence (green) combined with Hypoxyprobe-1staining (red) at day 0, 1, 3, 5, 7 and 14 post-implantation. Representative images were chosen from two to five mice analysed at each time point. The provided scale bars indicate 50 μm. Third, fourth and fifth row, endogenous glial cell behaviour. Direct eGFP fluorescence (green) combined with TOPRO3 staining (false colour representation in blue) and combined with immunofluorescence staining for ionized calcium binding adaptor molecule 1 (Iba1) (red, fourth row), S100 calcium binding protein B (S100B) (red, fifth row) or glial fibrillary acidic protein (GFAP) (red, sixth row) at day 0, 1, 3, 5, 7 and 14 post-implantation. Representative images were chosen from multiple stained slides (n = 3 for eGFP/TOPRO3/Iba1 combination, n = 3 for eGFP/TOPRO3/S100B combination and n = 1 for eGFP/TOPRO3/GFAP) per mouse analysed at each time point (n = 4/5). The provided scale bars indicate 50 μm for Iba1 and S100B images and 200 μm for GFAP images. Sixth row, graft site remodelling. Direct eGFP fluorescence (green) combined with myelin base protein (MBP) staining (red) at day 0, 1, 3, 5, 7 and 14 post-implantation. Representative images were chosen from multiple mice analysed at each time point (n = 2). The provided scale bars indicate 200 μm.
