Exosomes secreted by adipose-derived mesenchymal stem cells regulate type I collagen metabolism in fibroblasts from women with stress urinary incontinence

摘要

BackgroundMesenchymal stem cells (MSC) have gained credibility as a therapeutic tool partly due to their potential to secrete factors such as cytokines and chemokines. Recently, exosomes, which mediate intercellular communication by delivering biomolecules such as mRNA and miRNA into recipient cells, have gained attention as a new and valuable therapeutic strategy in regenerative medicine. However, the potential role of exosomes secreted by adipose-derived mesenchymal stem cells (adMSC-Exos) in collagen metabolism is not well understood. The purpose of this study was to evaluate the effects of adMSC-Exos on collagen metabolism in cultured fibroblasts from women with stress urinary incontinence (SUI).
