Mesenchymal Stem Cell Therapy in Kidney Diseases: Potential and Challenges

Area of Science:

• Nephrology
• Regenerative Medicine
• Stem Cell Biology

Background:

• Kidney disease (KD) presents significant clinical challenges with high morbidity and mortality, often exacerbated by aging.
• Current treatments like supportive therapy and kidney transplantation have limitations in halting KD progression.
• Mesenchymal stem cells (MSCs) possess regenerative capabilities, including differentiation and self-renewal, making them a promising therapeutic avenue.

Purpose of the Study:

• To review the biological characteristics of MSCs.
• To discuss the efficacy and underlying mechanisms of MSC-based therapies for KD.
• To summarize current clinical trials and explore future strategies for MSC transplantation in KD treatment.

Main Methods:

• Review of preclinical and clinical studies on MSCs for KD.
• Analysis of MSC mechanisms in ameliorating KD, including immune modulation, anti-apoptosis, anti-EMT, antioxidant, and pro-angiogenic effects.
• Examination of paracrine actions of MSCs in acute kidney injury (AKI) and chronic kidney disease (CKD).

Main Results:

• MSCs demonstrate significant therapeutic potential in preclinical and clinical settings for KD.
• MSC-based therapies effectively regulate immune responses, reduce renal cell apoptosis, inhibit epithelial-mesenchymal transition, combat oxidative stress, and promote angiogenesis.
• Paracrine mechanisms are key to MSC efficacy in both AKI and CKD.

Conclusions:

• MSCs represent a safe and effective therapeutic strategy for KD.
• Further research and clinical trials are warranted to optimize MSC transplantation for KD.
• Exploring new strategies and understanding limitations will advance MSC-based KD treatments.
