Edited course of biomedical research: leaping forward with CRISPR

Within the short few years since the report of its application in precise genome editing, CRISPR technology has become the method of choice to modify and modulate gene expression in biomedical research and therapeutic development. Subsequently, a variety of research, diagnostic, and therapeutic tools have been developed based upon CRISPR's mechanism of action. Such tools have helped to deepen the understanding of fundamental biology and broaden the horizon in the search for treatments for diseases that have been considered hard or impossible to cure. As CRISPR technology advances closer to clinical applications, its short comings are becoming more apparent, thus creating opportunities to improve the technology's efficacy, specificity, and safety profile in this setting. We will summarize the current status of CRISPR technology and discuss its future impact in this review.
