Figure Lengend Snippet: Mechanisms of NSC Differentiation into Neurons Promoted by Composite In Vitro. A) Schematic of the interactive system with NSCs and the composites. B) Representative confocal images of NSCs treated with distinct groups for 72 h. NSCs were stained with Tuj-1 (red), GFAP (green), and DAPI (blue). Scale bar: 50 μm. C-D) Quantitative analysis of Tuj-1 (C) and GFAP (D) fluorescence intensity in each group (n = 4). E) Western blot bands of Tuj-1 and GFAP protein expression in NSCs treated with separate groups. F-G) Quantitative analysis of Tuj-1/GAPDH (F) and GFAP/GAPDH (G) ratios in each group (n = 3). H) Volcano plots of DEGs in the hUCMSC-Exo + PM vs. control. DEGs are defined as |log2FC| ≥ 1 with q < 0.05. I-J) GO and KEGG pathway enrichment analysis of DEGs in NSCs after intervention with hUCMSC-Exo + PM. K) Heatmap showing the expression levels of significantly altered genes in the hUCMSC-Exo + PM and Control. L) GSEA showing pathways significantly positively correlated with DEGs in the hUCMSC-Exo + PM group. Enrichment scores (ES), P values, and false discovery rates (FDR) values are indicated for each pathway. M) Western blot bands of p-CaMK II, CaMK II, p-CREB, CREB, p-PI3K, PI3K, p-AKT, and AKT protein expression in NSCs treated with distinct groups. N) Quantitative analysis of p-CaMK II/CaMK II, p-CREB/CREB, p-PI3K/PI3K, and p-AKT/AKT ratios (n = 3). All data are presented as the mean ± SEM. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001, ∗∗∗∗p < 0.0001.
