RESUMO
South Asians, which represent around 25% of the world's population, have a disproportionately high risk of cardiometabolic disease, two-fold higher risk of myocardial infarction, and 4- to 6-fold higher risk for diabetes compared to Caucasians. We generated two induced pluripotent stem cell (iPSC) lines from healthy South Asian donors and validated the pluripotency and ability of these cell lines to differentiate into three germ layers. These iPSC lines can be applied to generate many cardiovascular cell types such as cardiomyocytes, endothelial cells, and mural cells to investigate different cardiovascular disease mechanisms triggered by environmental risk factors or drugs in vitro.

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.
