Steatosis and Phospholipidosis Imaging Analysis

Steatosis and Phospholipidosis Imaging Analysis

Steatosis refers to the accumulation of triglycerides (neutral fat) in the cytoplasm, which is often caused by nutritional disorders, infection, poisoning, and hypoxia. It usually occurs in tissues with strong metabolism and high oxygen consumption, such as hepatocytes, myocardial fibers, and renal tubular epithelium. Severe steatosis cells can develop into necrosis. Drug-induced steatosis is characterized by excess triglyceride accumulation in the form of lipid droplets in liver cells. Under the electron microscope, the fat in the cytoplasm of the cell appears as adipose bodies, which then fuse into lipid droplets.

Steatosis and Phospholipidosis Imaging Analysis

CD BioSciences can provide you with professional steatosis and phospholipidosis imaging analysis services. The lipid droplet-selective small-molecule fluorescent probes we developed can be used for one-photon and two-photon microscopes utilizing live cells or fixed cells. It provides a feasible method for screening potential steatosis and/or phospholipid degeneration drugs.

Steatosis and Phospholipidosis Imaging Analysis Workflow

Our steatosis and phospholipidosis imaging analysis combined high-content screening with 3D cell model to provide a medium-throughput method to screen test compounds to determine their potential to induce steatosis. The analysis steps are as follows.

Step 1

Cultivate the 3D hepatocyte model on the U-bottom plate to a diameter of about 200μm.

Step 2

Treatment of test compound and reference substance.

Step 3

Fix the 3D model and treat it for fluorescent labeling.

Step 4

The 3D model uses lipid stain to label lipids and phospholipids, and DAPI to label the nucleus.

Step 5

Perform high-content imaging and image analysis on well plates to quantify lipids and phospholipids in cell models.
