Author Interviews, Kidney Stones / 07.10.2017

MedicalResearch.com Interview with: Benjamin Freedman, Ph.D. Assistant Professor | University of Washington Department of Medicine | Division of Nephrology Member, Kidney Research Institute Member, Institute for Stem Cell and Regenerative Medicine Seattle WA 98109 MedicalResearch.com: What is the background for this new technology and study? What are the main findings? Response: Polycystic kidney disease (PKD) is the leading genetic cause of end stage renal disease, affecting approximately twelve million people. The hallmark of the disease is the massive expansion of kidney tubules into large, fluid-filled cysts. Although we know the genes that are mutated in this disease, we do not have a firm grasp on what they do to protect the body from disease. We used a new system, human kidney organoids with gene-edited PKD mutations, to discover how factors outside the cell affect cyst formation. We found that liberating the organoids from plastic dishes into floating cultures greatly increased the number and size of cysts that formed. We also found that PKD organoids had problems in their ability to change the shape of collagen scaffolds surrounding them, compared to control organoids of the same genetic background. (more…)
Author Interviews, Brigham & Women's - Harvard, Kidney Disease, Stem Cells / 20.11.2016

MedicalResearch.com Interview with: Dr. Ryuji Morizane MD, PhD Associate Biologist, Renal Division Brigham and Women’s Hospital Affiliated Faculty, Harvard Stem Cell Institute Instructor, Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Polycystic kidney disease (PKD) accounts for 10% of end-stage kidney disease (ESKD), and there is currently no curable treatment available for patients with PKD. The adult onset form of PKD, the most common type of PKD, takes 30 years to form cysts in humans; therefore, it is difficult to study mechanisms of PKD to find novel therapeutics for patients. (more…)
