Figure Legend Snippet: LT-NPs-NIR protects TSPCs against oxidative stress-induced senescence and preserves tenogenic phenotype. (A–D) Immunofluorescence staining for DNA damage (γ-H2AX), proliferation (Ki67), and senescence markers (P16, P53). (E–G) Assessment of stemness (SOX2) and tenogenic differentiation markers (SCX, COL1). (H) Quantitative analysis of the indicated markers. (I) qRT-PCR analysis of SASP-related inflammatory mediators (IL-1β, CXCL10) and matrix-degrading enzymes (MMP3, MMP13). (J) Schematic illustrating the mechanism of ROS scavenging and SASP inhibition. Significance: ns, not significant; ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001. Snt: senescent cells; Yng: young cells.
Techniques Used: Immunofluorescence, Staining, Quantitative RT-PCR, Inhibition
Figure Legend Snippet: LT-NPs-NIR modulate macrophage polarization and enhance TSPC-mediated tenogenic repair in a Transwell co-culture system. (A) Schematic of the Transwell co-culture setup. (B) SA-β-gal staining of macrophages. (C–F) Immunofluorescence of TSPCs for (C) P16, (D) SOX2, (E) SCX, and (F) Tenomodulin (TNMD) with F-actin. (G) Quantification of P16, SOX2, SCX, and TNMD levels. (H) Proposed mechanism: LT-NPs-NIR promote an M1-to-M2 macrophage shift and regulate TSPC senescence/stemness balance to favor tenogenic repair, potentially via STING/NF-κB signaling. Scale bars: 100 μm (B); 50 μm (C–E); 100 μm (F). Significance: ns, not significant; ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
Techniques Used: Co-Culture Assay, Staining, Immunofluorescence
Figure Legend Snippet: Molecular assessment of tendon repair and systemic biosafety. (A) Representative immunofluorescence images of inflammatory, matrix-degrading, tenogenic, and senescence markers, alongside macrophage phenotypes in repaired tendons. (B) Correlation analysis integrating molecular and functional recovery. Bar charts (left Y-axis) display the relative fluorescence intensity of the indicated markers, overlaid with line graphs (right Y-axis) showing the fold change in biomechanical properties (Ultimate Load and Tensile Modulus). Note the inverse correlation between SASP factors (IL-6, MMP13, P16) and mechanical strength. (C) Western blot analysis of the STING pathway, senescence indicators, and heterotopic ossification markers (OCN, SOX9, BMP-2). (D, E) Systemic biosafety evaluation via H&E staining of major organs (D) and blood biochemistry analysis (E) showing no toxicity. Significance: ns, not significant; ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
Techniques Used: Immunofluorescence, Functional Assay, Fluorescence, Western Blot, Staining
