Protocol to generate cardiac pericytes from human induced pluripotent stem cells

Cardiac pericytes are a critical yet enigmatic cell type within the coronary microvasculature. Since primary human cardiac pericytes are not readily accessible, we present a protocol to generate them from human induced pluripotent stem cells (hiPSCs). Our protocol involves several steps, including the generation of intermediate cell types such as mid-primitive streak, lateral plate mesoderm, splanchnic mesoderm, septum transversum, and epicardium, before deriving cardiac pericytes. With hiPSC-derived cardiac pericytes, researchers can decipher the mechanisms underlying coronary microvascular dysfunction. For complete details on the use and execution of this protocol, please refer to Shen et al.¹.
