Cholestasis Imaging Analysis

Cholestasis Imaging Analysis

Cholestasis is a pathophysiological process caused by the disorder of bile secretion and excretion. It is manifested in the excessive accumulation of bile components such as cholic acid, cholesterol and bilirubin in the liver and systemic circulation, resulting in damage to hepatocytes and the body. Long-term continuous cholestasis will progress to liver fibrosis and even liver cirrhosis. Imaging analysis is often used to check whether there is biliary obstruction and the specific cause of obstruction.

Cholestasis Imaging Analysis

Early lesions of the "downstream" bile duct lead to cholestasis and bile salt (BS) mediated "upstream" liver parenchymal toxic injury. Understanding the cellular physiology of bile secretion enables people to better grasp the cholestasis caused by various drugs. CD BioSciences can provide you with advanced cholestasis imaging analysis services. We use fluorescent bile acid probes and high-content imaging to directly measure BS accumulation, and then analyze the degree of bile duct expansion and contraction to evaluate the toxicity of candidate drugs.

Analysis method High content imaging
Cell types available HepaRG, HepG2
Primary human hepatocytes, primary cynomolgus monkey hepatocytes, primary canine hepatocytes
Cell model 2D cell monolayer
Sample requirements 50µL of 20 mM solution or equivalent amount of solid

Cholestasis Imaging Analysis Workflow

We use high-content imaging to analyze cholestasis caused by drug candidates, and the analysis steps are as follows:

Step 1

The cells were cultured to 80% confluent monolayer.

Step 2

Treatment with test compound.

Step 3

Addition of fluorescent bile acid probe.

Step 4

Cells were fixed and counterstained with DAPI.

Step 5

High content imaging and analyzing bile acid salt accumulation and bile duct size.
