چکیده

We introduce a simple microfluidic device that mimics function of the kidney proximal tubule by integrating a polydimethylsiloxane (PDMS) microfluidic channel and human proximal tubule cells on a porous extracellular matrix (ECM)coated porous membrane. This allows us to culture the kidney epithelial cells under a low level (0.2 dyne/cm) of fluid shear stress that mimics that of the normal kidney tubule. By providing in this system, a more physiological microenvironment, we are able to enhance epithelial cell polarization, cytoskeletal reorganization, primary cilia formation and response to renal toxins. These results suggest that our system is useful for studying human-relevant renal toxicity, and has the potential for drug development and advanced tissue engineering applications.

Human kidney proximal tubule-on-a-chip for drug transport and nephrotoxicity assessment.

Kidney toxicity is one of the most frequent adverse events reported during drug development. The lack of accurate predictive cell culture models and the unreliability of animal studies have created a need for better approaches to recapitulate kidney function in vitro. Here, we describe a microfluidic device lined by living human kidney epithelial cells exposed to fluidic flow that mimics key fu...

3D Proximal Tubule Tissues Recapitulate Key Aspects of Renal Physiology to Enable Nephrotoxicity Testing

Due to its exposure to high concentrations of xenobiotics, the kidney proximal tubule is a primary site of nephrotoxicity and resulting attrition in the drug development pipeline. Current pre-clinical methods using 2D cell cultures and animal models are unable to fully recapitulate clinical drug responses due to limited in vitro functional lifespan, or species-specific differences. Using Organo...

Development and Application of Human Renal Proximal Tubule Epithelial Cells for Assessment of Compound Toxicity

Kidney toxicity is a major problem both in drug development and clinical settings. It is difficult to predict nephrotoxicity in part because of the lack of appropriate in vitro cell models, limited endpoints, and the observation that the activity of membrane transporters which plays important roles in nephrotoxicity by affecting the pharmacokinetic profile of drugs is often not taken into accou...

A Microdosimetry model of kidney for nephrotoxicity due to internal radiation therapy

Introduction: We describe a nephron-based dosimetry model for renal toxicity for radiopharmaceutical therapy suited to the nonuniform activity distribution of radiopharmaceutical. In radiopharmaceutical therapy, renal toxicity is observed while whole-kidney and renal cortex absorbed dose values are below toxicity thresholds established by external beam and targeted radiope ptid...

Development of a microphysiological model of human kidney proximal tubule function.

The kidney proximal tubule is the primary site in the nephron for excretion of waste products through a combination of active uptake and secretory processes and is also a primary target of drug-induced nephrotoxicity. Here, we describe the development and functional characterization of a 3-dimensional flow-directed human kidney proximal tubule microphysiological system. The system replicates th...
