Figure Lengend Snippet: Cell autonomous VEGF signaling maintains NSCs in culture. a Diagram of the neighbor rescue experiment. b , c VEGF concentration (pg/ml) in NSC conditioned media after treatment with high MOI ( b ) or low MOI ( c ) mCherry or mCherryCre lentivirus. 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
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).
