title: Induced pluripotent stem cells as a next-generation biomedical interface.
abstract: Recent advances in DNA sequencing technologies and subsequent progress in genome-wide association study (GWAS) are rapidly changing the landscape of human diseases. Our knowledge on disease-gene linkage has been exponentially growing, and soon we will obtain complete maps of SNPs and mutations linked to nearly all major disease conditions. These studies will undoubtedly lead us to a more comprehensive understanding of how multiple genetic modifications link to human pathobiology. But what comes next after we discover these genetic linkages? To truly understand the mechanisms of how polygenic modifications identified through GWAS lead to disease conditions, we need an experimental interface to study their pathobiological effects. In this study, induced pluripotent stem cells (iPSCs), retaining all the genetic information from patients, will likely serve as a powerful resource. Indeed, pioneering studies have demonstrated that disease-specific iPSCs are useful for understanding disease mechanisms. Moreover, iPSC-derived cells, when recapitulating some disease phenotypes in vitro, can be a fast track screening tool for drug discovery. Further, with GWAS information, iPSCs will become a valuable tool to predict drug efficacy and toxicity for individuals, thus promoting personalized medicine. In this review, we will discuss how patient-specific iPSCs will become a powerful biomedical interface in clinical translational research.
