Renal diseases, particularly acute kidney injury (AKI) and chronic kidney disease (CKD), are significant global health challenges. These conditions impair kidney function and can lead to serious complications, including cardiovascular diseases, which further exacerbate the public health burden. Currently, the global AKI mortality rate is alarmingly high (20%-50%); CKD is projected to emerge as a major global health burden by 2040. Existing treatments such as hemodialysis and kidney transplantation have limited effectiveness and are often associated with adverse effects. Mesenchymal stem cells (MSCs) offer considerable potential for treating renal diseases owing to their regenerative and immunomodulatory properties. Thus, this review focuses on the application of MSCs in renal disease, discusses fundamental research findings, and evaluates their application in clinical trials. Moreover, we discuss the impact and safety of MSCs as a therapeutic option and highlight challenges and potential directions for their clinical application. We selected research articles from PubMed published within the last 5 years (from 2019), focusing on high-impact journals and clinical trial data, and included a few key studies predating 2019. Considerations included the novelty of the research, sample size, experimental design, and data reliability. With advancements in single-cell sequencing, CRISPR/Cas9 gene editing, and other cutting-edge technologies, future MSC research will explore combination therapies and personalized treatments to provide more promising, safer treatments with reduced adverse reactions and enhanced therapeutic outcomes. These advances will improve kidney disease treatment methods, enhance patient quality of life, and maximize the benefits of MSC therapies.
