Neonatal mouse-derived engineered cardiac tissue: a novel model system for studying genetic heart disease.
RATIONALE Cardiomyocytes cultured in a mechanically active 3-dimensional configuration can be used for studies that correlate contractile performance to cellular physiology. Current engineered cardiac tissue (ECT) models use cells derived from either rat or chick hearts. Development of a murine ECT would provide access to many existing models of cardiac disease and open the possibility of perfo...
متن کاملTissue Contraction Force Microscopy for Optimization of Engineered Cardiac Tissue.
We developed a high-throughput screening assay that allows for relative comparison of the twitch force of millimeter-scale gel-based cardiac tissues. This assay is based on principles taken from traction force microscopy and uses fluorescent microspheres embedded in a soft polydimethylsiloxane (PDMS) substrate. A gel-forming cell suspension is simply pipetted onto the PDMS to form hemispherical...
متن کاملTissue Engineered Scaffolds in Regenerative Medicine
Stem cells are self-renewing cells that can be differentiated into other cell types. Conventional in vitro models for studying stem cells differentiation are usually preformed in two-dimensional (2D) cultures. The design of three-dimensional (3D) in vitro models which ideally are supposed to mimic the in vivo stem cells microenvironment is potentially useful for inducing stem cell derived tissu...
متن کاملCardiac grafting of engineered heart tissue in syngenic rats.
BACKGROUND Cell grafting has emerged as a novel approach to treat heart diseases refractory to conventional therapy. We hypothesize that survival and functional and electrical integration of grafts may be improved by engineering cardiac tissue constructs in vitro before grafting. METHODS AND RESULTS Engineered heart tissue (EHT) was reconstituted by mixing cardiac myocytes from neonatal Fisch...
متن کاملTissue-Engineered Blood Vessels in Pediatric Cardiac Surgery
Pediatric cardiovascular surgeons often encounter patients requiring surgical intervention utilizing foreign materials to repair complex lesions. However, the materials that are commonly used lack growth potential, and long-term results have revealed several material-related failures, such as stenosis, thromboembolization, calcium deposition, and risk of infection. To solve these problems, in p...
