CAT-D’s mission is to develop microphysiological systems and use them for pre-clinical therapeutic discovery. These patient-specific “disease-in-a-dish” models will allow candidate therapies to be tested on disease tissues developed from a patient’s cells, thereby expediting pre-clinical studies and de-risking clinical trials.

Cardiac disease models

Our lead program is for cardiac disease. We have developed “heart-on-a-chip” models for cardiac contraction and cardiac arrhythmia.
