Background: No effective treatment guarantees full recovery from osteoarthritis (OA), and few therapies have disadvantages.
Aim: To determine if bone marrow mesenchymal stem cells (BMMSCs) and hyaluronic acid (HA) treat ankle OA in Wistar rats.
Methods: BMMSCs were characterized using flow cytometry with detection of surface markers [cluster of differentiation 90 (CD90), CD105, CD34, and CD45]. Fifty male Wistar rats were divided into five groups of 10 rats each: Group I, saline into the right tibiotarsal joint for 2 days; Group II, monosodium iodate (MIA) into the same joint; Groups III, MIA + BMMSCs; Group IV, MIA + HA; and Group V, MIA + BMMSCs + HA. BMMSCs (1 × 10 cells/rat), HA (75 µg/rat), and BMMSCs (1 × 10 cells/rat) alongside HA (75 µg/rat) were injected intra-articularly into the tibiotarsal joint of the right hind leg at the end of weeks 2, 3, and 4 after the MIA injection.
Results: The elevated right hind leg circumference values in the paw and arthritis clinical score of osteoarthritic rats were significantly ameliorated at weeks 4, 5, and 6. Lipid peroxide significantly increased in the serum of osteoarthritic rats, whereas reduced serum glutathione and glutathione transferase levels were decreased. BMMSCs and HA significantly improved OA. The significantly elevated ankle matrix metalloproteinase 13 (MMP-13) mRNA and transforming growth factor beta 1 (TGF-β1) protein expression, and tumor necrosis factor alpha (TNF-α) and interleukin-17 (IL-17) serum levels in osteoarthritic rats were significantly downregulated by BMMSCs and HA. The effects of BMMSCs and HA on serum TNF-α and IL-17 were more potent than their combination. The lowered serum IL-4 levels in osteoarthritic rats were significantly upregulated by BMMSCs and HA. Additionally, BMMSCs and HA caused a steady decrease in joint injury and cartilage degradation.
Conclusion: BMMSCs and/or HA have anti-arthritic effects mediated by antioxidant and anti-inflammatory effects on MIA-induced OA. MMP-13 and TGF-β1 expression improves BMMSCs and/or HA effects on OA in Wistar rats.

Objective: Abnormal mechanical stress is intimately coupled with osteoarthritis (OA). Microtubules play a vital role in the regulation of mechanotransduction and intracellular transport. The purpose of the present study was to investigate the impact of stress-induced microtubule impairment on intracellular transport and lipid droplet (LD) accumulation in chondrocytes.

Objective: This study aimed to explore the repair effect of siRNA-mediated double silencing of the mechanically sensitive ion channels Piezo1 and TRPV4 proteins on a rat model of osteoarthritis.
Methods: Piezo1 and TRPV4 interference plasmids were constructed using siRNA technology. Sprague Dawley (SD) rats were divided into four groups: the model group, siRNA-Piezo1, siRNA-TRPV4, and double gene silencing groups.

People with chronic pain mitigate their suffering by the action of opioids. Adverse reactions aside, opioids are not exempt from potential complications like addiction and abuse, which have posed a global public health problem lately. Finding new therapeutic strategies to improve analgesia and to reduce opioid side effects has become a priority.
