Cardiotoxicity Imaging Analysis

Cardiotoxicity Imaging Analysis

Cardiotoxicity characterized by severe cardiac dysfunction is a major problem for patients treated with different types of anticancer drugs. The current in vivo animal models and cell lines are not always sufficient to represent human biology. Therefore, it is important to develop methods and screening models for analyzing drug-induced cardiotoxicity. Human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM) have shown great potential in drug-induced cardiotoxicity analysis.

Cardiotoxicity Imaging Analysis

Traditional fluorescence-based high-throughput cardiotoxicity detection technology can analyze the average signal from many cells regardless of the cell heterogeneity in hiPSC-CM. In order to grasp the dynamics of the cell population, CD BioSciences can quantitatively analyze the cardiotoxicity of hiPSC-CM through a fully automated imaging analysis system. This high-throughput system performs single-cell segmentation through nuclear signal extraction, and provides a solution that focuses on single-cell analysis by providing phenotypic output (such as single cell number/morphological characteristics).

Cardiotoxicity Imaging Analysis Workflow

Most of the high-throughput image analysis used in hiPSC-CM research involves manual steps, mainly setting thresholds for positive signals or using commercial image analysis systems to segment individual cell nuclei. CD BioSciences uses fully automated high-throughput image analysis technology to analyze cytotoxicity. The detailed steps are as follows:

Step 1

Cell culture

The hiPSC-CM obtained on the 14th day of differentiation was thawed and seeded in a 96-well special optical plate in a humidified incubator at 37 ℃ and 5% CO2 for 24 hours.

Step 2

Add cardiac cytotoxicity inducer

HiPSC-CM used dimethyl sulfoxide as a control, treated with different concentrations of drugs for 4 days, and fixed in 2% paraformaldehyde for 30 minutes at room temperature.

Step 3


Use high-content imaging equipment to obtain images of cardiomyocytes under different conditions.

Step 4

Image analysis

ImageJ software was used for image analysis, and the cardiotoxicity of the drug was evaluated through experimental data.
