Doctors and researchers usually do not have many sources to study heart-related diseases. More treating methods could be discovered if the condition is changed.
Harvard University researchers bioengineered a more realistic artificial heart ventricle which would aid in the study of disease and treatment development.
This discovery will inspire more researchers to build different human organ models based on the same technology, leading to more potential treatment methods.
The research is still in the laboratory. Besides, the cost of an artificial 3-D model heart might be too high for researchers.
At present, human beings are faced with a number of heart-related diseases, which are often fatal. The lack of human heart resources has also slowed research into treatment. Researchers at Harvard University have created a 3-D model of a human left ventricle using nanofibers and human heart stem cells. This particular tissue can mimic the function of the heart. Nanofibers act as scaffolds for the model, and stem cells from the human heart make up the bulk of the model. Using this model, researchers can observe how the disease evolves and test the effects of the drug on the heart. From the point of view of bioengineering, the main difficulty of this achievement lies in the construction. By studying parallel myocardial fibers, researchers have found the key to building this model.
