text: * Intracoronary Administration of Bone Marrow-Derived Progenitor Cells: an in vivo technique in which progenitor cells derived from bone marrow are administered into an infarct artery to differentiate into functional cardiac cells and recover contractile function after an acute, ST-elevation myocardial infarction, thus preventing adverse remodeling of the left ventricle.
  * Human Cardiac Organoids:an in vitro, scaffold-free technique for producing a functioning cardiac organoid; cardiac spheroids made from a mixed cell population derived from human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) cultured on gelatin-coated well plates, without a scaffold, resulted in the generation of a functioning cardiac organoid
