    Article Title: An anti-senescence hydrogel with pH-responsive drug release for mitigating intervertebral disc degeneration and low back pain
    Article Snippet: After removing the working solution, three random fields of each group were imaged under an optical microscope and the proportion of β-Gal + cells were calculated using image J software (version: 1.52n, author: Wayne Rasband). .. At the designated time point, the cells were washed with PBS solution, fixed with 4 % paraformaldehyde for 15 min, followed by infiltration with 0.5 % Triton X-100 for 10 min. After being blocked with 5 % bovine serum albumin for 1 h, the samples were incubated with a primary antibody overnight at 4 °C (anti-aggrecan: 13880-1-AP, Proteintech, Wuhan, China, 1:400, 1.25 μg/mL; anti-Collagen Type II: 28459-1-AP, Proteintech, Wuhan, China 1:300, 1.67 μg/mL; anti-IL-1β: Abcam, ab283818, Cambridge, UK, 1:100, 5.3 μg/mL). .. After the primary antibody was removed, the samples were incubated with fluorescently conjugated secondary antibody in the dark at room temperature for 1 h. The cell nucleus was stained with Hoechst (Beyotime, Shanghai, China) for 5 min. Then, the samples were washed with PBS solution to remove unincorporated dyes.

    Article Title: Injectable chitosan microspheres resisting inflammatory and oxidative stress for ameliorating intervertebral disc degeneration
    Article Snippet: The treatment of intervertebral disc (IVD) degeneration remains a significant challenge due to the unique ischemic structure of the IVD, which comprises the scavenging of inflammatory cytokines, alleviation of cellular oxidative stress responses, restoration of nuclei pulposus (NP) cell viability, and recovery of IVD biomechanical function.. Herein, we developed an injectable microsphere (CS-MnO2@PC) by incorporating chitosan microspheres (CS) with manganese dioxide (MnO2) nanozymes and celecoxib encapsulated in Pluronic F-127 (PC) nanosized micelles, via in situ redox or Schiff base reaction.. The hybrid carrier demonstrates robust capabilities in scavenging free radicals, alleviating extracellular oxidative stress, and reducing inflammatory cytokines in NP cells, as evidenced by RT-qPCR and immunofluorescence staining assays.

    Article Snippet: Rat chondrocytes (P1) were seeded in 24-well plates (5 × 10 4 cells per well) and cultured to ∼70–80% confluence, stimulated with LPS (10 μg mL −1 , 12 h) to induce an inflammatory phenotype, and then treated with hydrogel extracts (Hy, AdHy, AdHy@Pae) for 24 h. Cells were washed three times with PBS, fixed in 4% paraformaldehyde for 15 min, permeabilized with 0.1% Triton X-100 (Aladdin, T434386) for 10 min, and blocked with 5% BSA (Solarbio, SW3015) at room temperature for 1 h. Primary antibodies were applied overnight at 4 °C: COL2A1 (Proteintech, 28459-1-AP, 1:200), SOX9 (HUABIO, HA723548, 1:1000), MMP9 (HUABIO, ET1704-69, 1:200), and ADAMTS5 (HUABIO, HA722011, 1:100).

    In vivo validation of the chondroprotective and mitochondrial regulatory effects of AdHy@Pae after therapy for 4 weeks. (A) Representative immunohistochemical staining of cartilage sections for COL2A1, SOX9, MMP3, and ADAMTS1 in different groups (Sham, PBS, Hy, AdHy, and AdHy@Pae). (B) Quantitative analysis of the immunohistochemical staining intensity showing relative expression levels of anabolic (COL2A1, SOX9) and catabolic (MMP3, ADAMTS1) markers. (C) TEM images of chondrocytes showing mitochondrial ultrastructure in each group, with high-magnification views (bottom panels) indicating cristae integrity and membrane morphology. Data are presented as mean ± SD (n = 3); ∗∗P < 0.01, ∗∗∗P < 0.001, ∗∗P < 0.0001.
