Abstract Stress urinary incontinence (SUI) is a prevalent pelvic floor dysfunction in women post-pregnancy. Currently, conservative treatment options have low success rates, while surgical interventions often result in multiple complications. The altered state of the extracellular matrix (ECM) is a pivotal factor in the onset of various diseases and likely plays a significant role in the pathogenesis of SUI, particularly through changes in collagen and elastin levels. Recent advances in mesenchymal stem cells (MSCs) therapy have shown considerable promise in treating SUI by modulating ECM remodeling, thereby enhancing the supportive tissues of the female pelvic floor. MSCs exhibit substantial potential in enhancing urethral sphincter function, modulating connective tissue architecture, and stimulating fibroblast activity. They play a pivotal role in the reconstruction and functional recovery of the ECM by influencing various signaling pathways, including TGF-β/SMAD, JAK/STAT, Wnt/β-catenin, PI3K/AKT, and ERK/MAPK. We have reviewed the advancements in MSC-mediated ECM metabolism in SUI and, by integrating the functions of ECM in other diseases and how MSCs can ameliorate conditions through their impact on ECM metabolism, we have projected the future trajectory of SUI treatment development.
