Abstract
Induced pluripotent stem cells (iPSCs) exhibit an unlimited ability to self-renew and produce various differentiated cell types, thereby creating high hopes for both scientists and patients as a great tool for basic research as well as for regenerative medicine purposes. The availability and safety of iPSCs for therapeutic purposes require safe and highly efficient methods for production of these cells. Different methods have been used to produce iPSCs, each of which has advantages and disadvantages. Studying these methods would be very helpful in developing an easy, safe, and efficient method for the generation of iPSCs. Since iPSCs can be generated from somatic cells, they can be considered as valuable cellular resources available for important research needs and various therapeutic purposes. Coronavirus disease 2019 (COVID-19) is a disease that has endangered numerous human lives worldwide and currently has no definitive cure. Therefore, researchers have been rigorously studying and examining all aspects of COVID-19 and potential treatment modalities and various drugs in order to enable the treatment, control, and prevention of COVID-19. iPSCs have become one of the most attractive and promising tools in this field by providing the ability to study COVID-19 and the effectiveness of drugs on this disease outside the human body. In this study, we discuss the different methods of generation of iPSCs as well as their respective advantages and disadvantages. We also present recent applications of iPSCs in the study and treatment of COVID-19.

Abstract
Translating human induced pluripotent stem cell (hiPSC)-derived cells and tissues into the clinic requires streamlined and reliable production of clinical-grade hiPSCs. This article describes an entirely animal component-free procedure for the reliable derivation of stable hiPSC lines from donor peripheral blood mononuclear cells (PBMCs) using only autologous patient materials and xeno-free reagents. PBMCs are isolated from a whole blood donation, from which a small amount of patient serum is also generated. The PBMCs are then expanded prior to reprogramming in an animal component-free erythroblast growth medium supplemented with autologous patient serum, thereby eliminating the need for animal serum. After expansion, the erythroblasts are reprogrammed using either cGMP-grade Sendai viral particles (CytoTune™ 2.1 kit) or episomally replicating reprogramming plasmids (Epi5™ kit), both commercially available. Expansion of emerging hiPSCs on a recombinant cGMP-grade human laminin substrate is compatible with a number of xeno-free or chemically defined media (some available as cGMP-grade reagents), such as E8, Nutristem, Stemfit, or mTeSR Plus. hiPSC lines derived using this method display expression of expected surface markers and transcription factors, loss of the reprogramming agent-derived nucleic acids, genetic stability, and the ability to robustly differentiate in vitro to multiple lineages. © 2020 by John Wiley & Sons, Inc.
