Heart on Chip Tissue Microfluidic Platform
Cardiovascular disease (CVD) is the leading cause of death around the world, resulting in more than 17.9 million deaths in 2016. Thus, it is vitally important to advance therapies and drugs that can help in the treatment of CVD. Even with an uptick in R&D efforts toward CVD therapies, success has been limited, with many efforts thwarted in the preclinical stages. Preclinical models have a difficult time recreating and simulating the in vivo dynamics of the heart and surrounding environment.
Recently organ on chip technologies have emerged as powerful systems for disease modeling, tissue development, drug screening, therapy design and potentially organ replacement. While there has been increased activity in the development of 3D or heart on chip platforms, these models have yet to produce physiologically relevant anisotropic cardiac tissue, and are unable to induce or mimic physiological conditions of specific cardiac diseases. Further, none of these platforms have provided precise mechanistic insight into the phenotypic signatures of cardiac cells and the physiological alterations of myocardium from a healthy to diseased state.
Researchers at Arizona State University have developed a physiologically relevant 3D cardiac tissue microfluidic platform with precisely engineered architecture and surface topography. This platform enables 3D tissue culture with optimized tissue-level alignment, similar to that seen in native human myocardium, over an extended period of time. It provides physiologically relevant disease modeling and drug testing as well as sample collection for appropriate phenotypic and genotypic analyses. Pathological events involved in the transition of healthy to diseased cardiac tissue can be better studied with this model. Additionally, the design allows it to recapitulate specific disease conditions such as acute and chronic ischemia.
This platform overcomes the technical limitations of existing heart on chip systems and provides a powerful approach for both mechanistic studies and pre-clinical applications.
• Cardiac injury/disease modeling
