Kidney Toxicity Imaging Analysis

Kidney Toxicity Imaging Analysis

The kidneys play an important role in maintaining the homeostasis of the body's internal environment, including regulating water, electrolyte, nitrogen, and acid-base balance. They also control red blood cell production and blood pressure. Impaired renal function is common in clinical practice and is usually related to the use of drugs. Therefore, early prediction of drug nephrotoxicity is very important for drug development and market entry.

Kidney Toxicity Imaging Analysis

An in vitro model was developed to reliably predict the nephrotoxicity of potential drugs. The two-dimensional culture of primary or conditionally immortalized renal epithelial cells represents the gold standard of traditional in vitro model for nephrotoxicity evaluation. However, proximal tubular epithelial cells cultured with this method exhibit poor apical-basal polarization and low levels of key protein transporters, which hinder their utility as a tool for predicting drug nephrotoxicity.

In order to bypass the limitations of 2D culture, CD BioSciences uses the advanced in vitro culture system that has been developed, including organoids and renal micro physiological system that can reproduce the characteristics of fluids in the body to simulate in vivo tissues, so as to provide a reliable tool for nephrotoxicity assessment in the early stage of drug development.

Kidney Toxicity Imaging Analysis Workflow

We use the high-content imaging analysis system to provide you with drug nephrotoxicity analysis services for human renal proximal tubule epithelial cells. The detailed steps are as follows:

Step 1

Cultivate renal proximal tubule epithelial cells to create 3D models.

Step 2

Treat 3D models with test compound.

Step 3

Tissue removal and performs high-content imaging.

Step 4

Analyze the experimental data and evaluate nephrotoxicity of the drug.
