Stem Cell Therapies in Kidney Diseases: Progress and Challenges

Area of Science:

• Nephrology
• Regenerative Medicine
• Stem Cell Biology

Background:

• Renal diseases pose a significant public health challenge with high mortality rates.
• Current supportive therapies for kidney injury have limitations.
• Stem cell technology offers a novel strategy for stimulating kidney regeneration.

Purpose of the Study:

• To summarize the renoprotective potential of stem cell therapy in experimental kidney injury models.
• To explore mechanisms of stem cell-induced kidney regeneration.
• To discuss the translation of experimental findings into clinical applications.

Main Methods:

• Review of experimental models of acute and chronic kidney injury.
• Analysis of pluripotent and adult stem cell therapy mechanisms.
• Evaluation of stem cell secretome-derived bioproducts for cell-free therapy.
• Assessment of safety and feasibility for clinical trials.

Main Results:

• Stem cells, including embryonic, induced pluripotent, mesenchymal stem cells, and renal precursors, demonstrate renoprotective effects.
• Mechanisms include cell engraftment, incorporation into renal structures, and paracrine activities.
• Stem cell secretome and extracellular vesicles show potential for cell-free regenerative therapy.

Conclusions:

• Stem cell therapy is a promising strategy for treating kidney injury.
• Both cell-based and cell-free approaches warrant further investigation.
• Clinical translation holds potential for improving outcomes in patients with kidney disease.
