Figure Lengend Snippet: Effect and mechanism of the nano-gelatin on NSCs . (A) A diagram of the layered composite structure of the nano-gelatin after hemostasis. (B) Representative SEM images showing the platelet-derived extracellular vesicles in the nano-gelatin after hemostasis. (C) ALB contents in the cryogels following hemostasis (N = 4). (D) NGF contents in the cryogels (N = 3). (E) SDF-1 contents in the cryogels (N = 3). (F) Representative images showing NSCs migrating through the Transwell membrane into the plate with cryogels. (G) Quantification of the NSC numbers that migrated through the Transwell membrane into the plate (N = 4). (H) Representative images of the live/dead staining showing the survival and morphology of NSCs on the cryogels. (I) Cytotoxicity of the cryogels on NSCs by CCK-8 assay. (J) Representative images of immunostaining against F-actin, paxillin, and vinculin for cells encapsulated in the nano-gelatin and the GelMA hydrogel. (K) Representative images of immunostaining against Tuj-1 and GFAP. (L) Volcano plot analyzing DEGs between the nano-gelatin group and the control group. (M) The enriched GO pathways. (N) The enriched KEGG pathways. (O) The heatmaps of DEGs associated with Focal adhesion. (P) Schematic diagram of the potential mechanism by which the nano-gelatin regulates NSC migration and differentiation to promote nerve repair. Statistical analysis was performed using one-way ANOVA followed by Tukey's multiple comparisons test.

Article Snippet: Then, the samples were fixed and stained with astrocyte marker GFAP (1:500, CST, Rabbit mAb #80788) and neuron marker Tuj-1 (1:200, HUABIO, SP06-00) to assess differentiation.
