Deconvoluting the Cells of the Human Heart with iPSC Technology: Cell Types, Protocols, and Uses.

PURPOSE OF REVIEW

Induced pluripotent stem cells (iPSCs) have become widely adopted tools in cardiovascular biology due to their ability to differentiate into patient-specific cell types. Here, we describe the current protocols, important discoveries, and experimental limitations from the iPSC-derived cell types of the human heart: cardiomyocytes, cardiac fibroblasts, vascular smooth muscle cells, endothelial cells, and pericytes. In addition, we also examine the progress of 3D-based cell culture systems.

RECENT FINDINGS

There has been rapid advancement in methods to generate cardiac iPSC-derived cell types. These advancements have led to improved cardiovascular disease modeling, elucidation of interactions among different cell types, and the creation of 3D-based cell culture systems able to provide more physiologically relevant insights into cardiovascular diseases. iPSCs have become an instrumental model system in the toolbox of cardiovascular biologists. Ongoing research continues to advance the use of iPSCs in (1) disease modeling, (2) drug screening, and (3) clinical trials in a dish.
