Human Cardiac Organoids: Quantification and Qualification in Cardiovascular Studies

The human cardiac organoids (hCOs) represent a three-dimensional (3D) tissue model that mirrors in vivo cardiac conditions. Recent advancements underscore the immense potential of hCOs in several areas including studying early cardiogenesis, modeling heart diseases, screening potential drugs, and even exploring possibilities for cardiac regeneration. Recognizing the pivotal role hCOs play across various applications, this review examines the evolution of key metrics and tools for assessing cardiac organoids tailored for diverse research objectives. Moreover, it deliberates on the limitations of cardiac organoids and outlines the prospective avenues for future research applications of hCOs.
