Core Viewpoint - Osteoarthritis (OA) is a degenerative joint disease primarily affecting the elderly, characterized by the degradation of articular cartilage and subsequent joint pain and limited mobility. Current treatments include non-steroidal anti-inflammatory drugs and, in severe cases, total joint replacement [2]. Group 1: Treatment Innovations - The FDA has recently approved Matrix-associated Autologous Chondrocyte Implantation (MACI) for repairing isolated cartilage injuries in patients aged 18-55, indicating that cell therapy may become an effective treatment for osteoarthritis [3]. - Procr chondroprogenitors, identified in a study published in Cell, are sensitive to mechanical stimuli and play a crucial role in maintaining and regenerating articular cartilage, presenting a promising cell source for treating degenerative orthopedic diseases like osteoarthritis [4][9]. Group 2: Research Findings - The study found that mechanical stimulation from forced running significantly increased the number of Procr+ cells, while mechanical unloading decreased their numbers. OA activates Procr+ cells to repair cartilage erosion, and their genetic knockout accelerates OA progression [6]. - Inhibition of the mechanosensor Piezo1 significantly impairs the cartilage repair function of Procr+ cells, while intra-articular injection of Piezo1 agonists improves OA symptoms [6]. - Purified Procr+ superficial cells, after expansion and in vivo transplantation, can effectively repair cartilage defects, highlighting their potential as a reliable cell source for treating knee joint diseases like osteoarthritis [9].

Core Viewpoint - The research team at Tianjin University has developed a novel streamlined zinc oxide composite injectable hydrogel that opens new pathways for the treatment of osteoarthritis and cartilage regeneration [1][2] Group 1: Hydrogel Characteristics - The hydrogel exhibits dual characteristics of being "smooth during injection" and "firm after implantation" [1] - The streamlined zinc oxide structure optimizes the rheological and mechanical properties of the hydrogel, providing high mechanical strength and low flow viscosity [1][2] Group 2: Mechanism and Functionality - The hydrogel addresses the critical issue of extracellular matrix homeostasis imbalance in osteoarthritis treatment by incorporating matrix metalloproteinase-responsive features and delivering the miR-17-5p gene drug [1] - miR-17-5p is a small RNA molecule that effectively inhibits the overactive matrix metalloproteinases responsible for excessive degradation of the extracellular matrix [1] Group 3: Injection and Performance - The internal streamlined zinc oxide nanoparticles reduce fluid resistance during injection, allowing for smoother passage through the injection needle and rapid filling of irregular tissue defects [2] - Upon injection, the hydrogel undergoes a cross-linking reaction, forming a stronger network structure that enhances its mechanical performance and resistance to external mechanical stress [2] Group 4: Gene Therapy Implications - The streamlined structure significantly improves the transfection efficiency of miR-17-5p, providing new insights for precise delivery in gene therapy [2] - This design not only reduces energy loss during the injection process but also greatly enhances the hydrogel's supporting capacity at tissue defect sites, ensuring long-term treatment efficacy and structural integrity [2]
