Tissue engineering of functional cardiac muscle: molecular, structural, and electrophysiological studies.
The primary aim of this study was to relate molecular and structural properties of in vitro reconstructed cardiac muscle with its electrophysiological function using an in vitro model system based on neonatal rat cardiac myocytes, three-dimensional polymeric scaffolds, and bioreactors. After 1 wk of cultivation, we found that engineered cardiac muscle contained a 120- to 160-microm-thick periph...
متن کاملCardiac muscle tissue engineering: toward an in vitro model for electrophysiological studies.
The objective of this study was to establish a three-dimensional (3-D) in vitro model system of cardiac muscle for electrophysiological studies. Primary neonatal rat ventricular cells containing lower or higher fractions of cardiac myocytes were cultured on polymeric scaffolds in bioreactors to form regular or enriched cardiac muscle constructs, respectively. After 1 wk, all constructs containe...
متن کاملEngineering Cardiac Muscle Tissue
The origin of the term tissue engineering is not clear, but a 1985 proposal of Y.C. Fung to the National Science Foundation of the United States for a Center for the Engineering of Living Tissues and 2 conferences organized by the National Science Foundation in 1987 and 1988 are generally accepted as the origin of this lively and rapidly growing research field (The Emergence of Tissue Engineeri...
متن کاملApplications of Small Molecules in Muscle Tissue Engineering
Introduction: Skeletal muscles account for about 40% of the total body weight. Every year, hundreds of people lose at least part of their muscle tissue due to illness, war, and accidents. This can lead to disruption of activities such as breathing, movement, and social life. To this end, various therapeutic strategies such as medication therapy, cell therapy and tissue transplantation have been...
متن کاملCardiomyocyte cultures with controlled macroscopic anisotropy: a model for functional electrophysiological studies of cardiac muscle.
Structural and functional cardiac anisotropy varies with the development, location, and pathophysiology in the heart. The goal of this study was to design a cell culture model system in which the degree, change in fiber direction, and discontinuity of anisotropy can be controlled over centimeter-size length scales. Neonatal rat ventricular myocytes were cultured on fibronectin on 20-mm diameter...
