Generation of nine induced pluripotent stem cell lines as an ethnic diversity panel.

Human induced pluripotent stem cells (iPSCs) provide a potentially unlimited source of differentiated cells from individuals with specific genetic backgrounds. Using self-replicative RNA reprogramming technology, we generated nine iPSC lines from endothelial progenitor cells (EPCs) derived from blood samples of three different ethnicities: Black or African American, Latino or Hispanic, and Non-Hispanic White. The resulting iPSC lines showed normal karyotype in large part, expressed pluripotency marker genes, and spontaneously differentiated in vitro into the three germ layers. These iPSC lines offer the potential to generate tissues with ethnic diversity, and thus afford a valuable tool for ethnic-related toxicological applications.
