Figure Lengend Snippet: In vitro evaluation of the osteogenic-promoting capability of BTO@ALN. (A–D) Immunofluorescence staining of osteoblasts differentiated from primary mouse bone marrow–derived mesenchymal stem cells (BMSCs) (red: actin; green: RUNX2 and ATF4) and corresponding quantitative analysis of fluorescence intensity. (E–H) Alkaline phosphatase (ALP) and Alizarin Red S (ARS) staining of osteoblasts derived from primary mouse BMSCs and quantitative analysis of staining intensity.

Figure Lengend Snippet: RNA-seq profiling of human adipose-derived stem cells (hASCs) after 21 days of culture in myogenic differentiation medium. (a) Principal component analysis (PCA) based on transcriptome expression values (FPKM), showing clustering of biological replicates for Monolayer (2D), PCL, and Fibril conditions. (b) Venn diagram showing the overlap of detected genes among Monolayer, PCL, and Fibril groups (numbers indicate gene counts in each intersection). (c) Gene Ontology (GO) Biological Process (BP) over-representation analysis (ORA) for differentially expressed genes in 2D vs nFMBs (left) and PCL-mFiBs vs nFMBs (right); bars are plotted as −log10 (adjusted p value), with terms enriched among genes upregulated in the first condition shown to the right (red) and terms enriched among genes downregulated in nFMBs shown to the left (blue). (d) KEGG pathway enrichment analysis for differentially expressed genes between PCL-mFiBs and nFMBs groups; dot size represents the number of genes mapped to each pathway (Count), dot color indicates adjusted p value, and the x-axis denotes Gene Ratio. (e) Category network plot (CNP; category–gene network plot) for the PCL-mFiBs vs nFMBs comparison, visualizing representative enriched GO BP terms and their associated genes; gene nodes are colored by fold change and term nodes reflect enrichment significance. (f–i) Heatmaps of selected genes associated with representative GO terms: GO:0000280 (nuclear division), GO:0030198 (extracellular matrix organization), GO:0003012 (muscle system process), and GO:0007519 (skeletal muscle tissue development), respectively; expression patterns are shown across 2D, PCL-mFiBs, and nFMBs, with gene symbols listed alongside each heatmap.
