Michigan State University researchers have created for the first time a miniature human heart model in the laboratory, complete with all primary heart cell types and a functioning structure of chambers and vascular tissue.
In the United States, heart disease is the No. 1 cause of death. “These minihearts constitute incredibly powerful models in which to study all kinds of cardiac disorders with a degree of precision unseen before,” said Aitor Aguirre, the study’s senior author and assistant professor of biomedical engineering at MSU’s Institute for Quantitative Health Science and Engineering.
This study, “Generation of Heart Organoids Modeling Early Human Cardiac Development Under Defined Conditions,” appears on the bioRxiv preprint server.
