Figure Lengend Snippet: (a) Hydrogels scans of U87-GFP GBM cells migration at t = 0 h, t = 24 h and t = 120 h with and without CXCL12 at a flow rate of 0.5 μL/min. (b) Hoechst staining of the hydrogels at t = 120 h. (c) DNA quantification of the different hydrogel sections at the end of the experiment (N = 9, n = 3). Bars represent the mean ± SD and the squares are zoom regions. Statistical analysis was conducted using a Kruskal-Wallis test followed by Dunn’s multiple comparison post-hoc test, * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001. 1 : (Alg:M + cells NPs-Empty vs. Alg:M + cells NPs-CXCL12) *, (Alg:M + cells NPs-Empty vs. Alg:M + cells NPs-CXCL12+) *, (Alg:M + cells NPs-CXCL12 vs. Alg:M + cells NPs-CXCL12+) ns. 2 : (Alg:M NPs-Empty vs. Alg:M NPs-CXCL12) ns, (Alg:M NPs-Empty vs. Alg:M NPs-CXCL12+) **, (Alg:M NPs-CXCL12 vs. Alg:M NPs-CXCL12+) ns. 3 : (Alg:M NPs-Empty vs. Alg:M NPs-CXCL12) ns, (Alg:M NPs-Empty vs. Alg:M NPs-CXCL12+) ***, (Alg:M NPs-CXCL12 vs. Alg:M NPs-CXCL12+) ns. 4 : (Alg:M + cells NPs-Empty vs. Alg:M + cells NPs-CXCL12) ns, (Alg:M + cells NPs-Empty vs. Alg:M + cells NPs-CXCL12+) ns, (Alg:M + cells NPs-CXCL12 vs. Alg:M + cells NPs-CXCL12+) **. The scale bar represents 2000 μm. NPs-Empty: Alginate/Chitosan-Nanoparticles unloaded; NPs-CXCL12: Alginate/Chitosan Nanoparticles loaded with CXCL12; Alg:M: Alginate:Matrigel (50:50); Alg 1%: Alginate 1% hydrogel.
Article Snippet: Human recombinant CXCL12 (SDF-1α) (purity ≥98%, PeproTech United States, Rocky Hill, NJ, United States) was reconstituted in sterile Milli-Q water following the manufacturer’s instruction.
