The Kidney, Volume 7in the Stem Cell Innovation in Health and Disease series explores the emerging potential of stem cell therapies in treating kidney diseases. With their natural regenerative and anti-inflammatory properties, stem cells offer a promising approach to restoring essential kidney functions and mitigating damage. This volume highlights how stem cell therapies may modulate immune responses, promote tissue repair, and replace damaged kidney cells, offering hope for chronic and acute renal conditions. Key developments include the injection of mesenchymal stem cells (MSCs) into damaged kidneys, where they can differentiate into kidney cell types and aid in healing. Urine-derived stem cells have also shown significant potential in improving kidney function in preclinical studies. Additionally, innovative techniques like incorporating MSCs into compact dialysis machines are being explored, enabling delivery of pro-repair factors directly to the kidneys during blood filtration. While there are currently no FDA-approved stem cell treatments for kidney diseases, ongoing clinical trials aim to evaluate their safety and efficacy. This volume compiles cutting-edge research, discussing various cell sources, underlying mechanisms, observed therapeutic outcomes, and the practical challenges of clinical translation. By presenting a clear picture of current advances and future directions, The Kidney serves as a vital resource for scientists, clinicians, and health innovators seeking to harness stem cell technology in nephrology. Provides cutting-edge research to understand stem cell functions used in disease and disorder treatments of the kidney Develops processes to bring stem cells from bench to bedside Includes up to date references on stem cell biology and function in common kidney diseases and disorders
