Toward a CRISPR Picture: Use of CRISPR/Cas9 to Model Diseases in Human Stem Cells In Vitro

Abstract

Human induced pluripotent stem cells (iPSCs) can be differentiated into any cell in the body unlocking enormous research potential. Combined with the recent discovery of CRISPR/Cas9 endonucleases in bacteria and their modification for use in biomedical research, these methods have the potential to revolutionize the field of genetic engineering and open the door to generating in vitro models that more closely resemble the in vivo system than ever before. Use of CRISPR/Cas9 has created a whirlwind within the scientific community in the last few years, as the race to move beyond just disease analysis and toward the goal of gene and cell therapy moves further. This review will detail the CRISPR/Cas9 method and its use in stem cells as well as highlight recent studies that demonstrate its use in creating robust disease models. Finally, recent results and current controversies in the field are reviewed and lingering challenges to further development are explored. J. Cell.
