Induced pluripotent stem cells (iPSCs) are generated from terminally differentiated cells and have the potential to differentiate to any organs originated from the embryonic germ layers. Extensive effort has been made to establish protocols for direct in vitro conversion of human iPSCs (hiPSCs) to different cell types/organs. Importantly, hiPSCs can be generated from patients with known genetic mutations that predispose to high-risks of specific disease development. Thus, the hiPSCs technology provides unlimited resources for creating patient-specific disease models. hiPSC-derived three-dimensional “organoid” models have recently emerged as a powerful tool to recapitulate the physiologically-relevant process of disease progression in vitro. In this chapter, we will discuss the current advancement of organoid regeneration from hiPSCs and the applications of hiPSCs-derived organoids. The limitations and challenges of this approach will also be discussed here.
