Figure Legend Snippet: Establishment of zebrafish cartilage injury and mouse OA models and therapeutic evaluation of antidiabetic drugs, including semaglutide. A. The diagrams show the Tg(col2a1a:dendra2-NTR) transgenic line and its labeling of mandibular cartilages, including Meckel's cartilage (M), palatoquadrate cartilage (Pq), and ceratohyal cartilage (Ch). B. The flowchart illustrates the process of cartilage injury and drug treatment in zebrafish: at 3.5 days post-fertilization (dpf), zebrafish larvae were exposed to 12 mM metronidazole (MTZ) for 20 h, followed by drug intervention, with phenotypic analysis performed 3 days later. C. Representative gross morphology of zebrafish in the MTZ/NTR-induced cartilage injury repair model. D. Confocal microscopy analysis showing the repair effects of different antidiabetic drugs on zebrafish cartilage injury (n = 10). The antidiabetic agents included metformin (Met), empagliflozin (Emp), rosiglitazone (Ros), gliclazide (Gli), and semaglutide (Se). Working concentrations were selected based on published doses and further refined in pilot assays to identify the highest effective concentration that did not cause overt toxicity or teratogenic effects. E. Experimental design of Se administration in wild-type (WT) mice with DMM-induced osteoarthritis (OA). F. Body weight changes in WT mice during treatment with low- or high-dose Se following destabilization of the medial meniscus (DMM) surgery (n = 6). G. Mechanical allodynia in each group of WT mice was assessed using the von Frey test during Se treatment after DMM surgery (n = 6). H. Effects of Se on pain-related behavior in OA mice, along with representative gait footprints from each group. I. Quantitative gait analysis based on H-track parameters, expressed as the ratio of right hindlimb to left hindlimb (RH/LH) (n = 6). J. Representative micro-computed tomography (micro-CT) images of knee joints from each group, including sagittal, coronal, and transverse reconstructions, illustrate overall subchondral bone alterations following Se treatment. K. Quantitative analysis of subchondral bone structural parameters derived from micro-CT images in (J), including subchondral bone plate (SBP) thickness, bone volume fraction (BV/TV), and trabecular thickness (Tb.Th) (n = 6). Scale bar represents 100 μm. Data are presented as the means ± SD. ns. Non-significant. ∗P value < 0.05. ∗∗P value < 0.01. ∗∗∗P value < 0.001.
