Figure Lengend Snippet: VEGFR2 and VEGF are expressed in the same NSCs. a Kdr and Vegfa in situ hybridization co-labeled with GFAP antibody in adult mouse DG. Scale bar represents 10 µm. b Percent of putative RGL-NSCs that are Kdr + , Vegfa + , or Kdr + / Vegfa + by in situ hybridization coupled with immunolabeling for GFAP. N = 4 mice; mean ± SEM. c Representative immunofluorescent image of VEGFR2 immunolabeling with Nestin in a VEGF-GFP mouse. Arrowheads show VEGFR2 + /VEGFGFP + /Nestin + co-expression. Scale bar represents 20 µm. d Representative 3D renderings of z-stack images of VEGFA and VEGFR2 immunoreactivity in the ER (PDI) or Golgi (RCAS1, Syntaxin) in permeabilized cultured NSCs. Hoechst labels nuclei. Major lines in image boxes are 10 µm apart

Article Snippet: The following day, after three rinses in PBS, cells were incubated in secondary antibodies diluted in blocking solution for 2 h. If a biotinylated secondary was used, a fluorophore-conjugated tertiary was applied for 1 h diluted in PBS before rinsing and nuclei counterstaining with Hoechst (10 min, 1:2000 in PBS) (Invitrogen).

N = 3 wells/grp; mean ± SEM plus individual wells shown. d Representative immunofluorescent images of BrdU + cultured Vegfa lox/lox and WT NSCs (Hoechst + ) after lentiviral infection (mCherry + ). Chevrons indicate BrdU + mCherry + Hoechst + NSCs. e Percent of mCherry + or mCherry − Vegfa lox/lox and WT NSCs that were BrdU + after low MOI mCherryCre and mCherryonly lentiviral infection. N = 3/grp/exp, 3 exps. Mean ± SEM shown. f Representative images of cultured Vegfa lox/lox NSCs (brightfield) after lentiviral infection (mCherry + ) after 1 and 4 passages. Images taken immediately after passage, when counting was performed. g Representative images of cultured WT NSCs (brightfield) after lentiviral infection (mCherry + ) after 1 and 4 passages. Images taken immediately after passage, when counting was performed. h Percent of mCherry + Vegfa lox/lox and WT NSCs after infection with low MOI mCherryCre or mCherryonly lentiviral vectors. N = 3/grp/exp, 2 exps; mean ± SEM. Scale bars represent d 10 µm and f , g 50 µm. * p < 0.05; ** p < 0.01; **** p < 0.0001
