Development Of Novel Crispr Technologies For The Precise Genome Editing Of Human Pluripotent Stem Cells

Precision genome surgery has the potential to revolutionize the field of personalized medicine through applications ranging from basic science, to creation of in vitro disease models, all the way to the correction of genetic disease in vivo. Although the field has rapidly advanced since the development of CRISPR-based technology, the ability to generate precise edits at multiple locations within the genome remains an outstanding challenge. As a result, edited cell populations as well as isolated clones must be rigorously screened for the presence of undesired mutations before any form of clinical application such as ex vivo cell therapy or in vivo somatic cell editing can be undertaken. Thus, there is a need to increase rates of precise editing and decrease rates of imprecise mutation to improve the clinical viability of gene editing. This thesis aims to develop new technologies to address challenges in precision genome editing and subsequently demonstrate their utility in a human pluripotent stem cell disease model. First, I describe a method to track hundreds of cell populations in real time using high-content analysis, allowing the facile selection of those that have undergone genome editing. Second, I demonstrate a new technology that is capable of tethering together CRISPR ribonucleoproteins and donor DNA to increase the frequency of precise gene surgery. Finally, I combine these technologies to correct mutations in an induced pluripotent stem cell model of Pompe disease, an autosomal recessive disorder. These methods and their applications demonstrate advances in the field of precision genome surgery and represent an important step toward the clinical use of genetic therapies.

CRISPR Genome Surgery in Stem Cells and Disease Tissues focuses uniquely on the clinical applications of CRISPR/Cas9 based technology. Topics include the latest advances in gene editing and its translational applications to various diseases, including retinal degenerative disease, recessively inherited diseases, and dominantly inherited diseases, to name a few. The book's target audience includes researchers, students, clinicians and the general public. This space that is not currently served by any existing resource, so this publication fills a gap in current literature. Provides a thorough review of CRISPR-Cas9, from discovery to therapy Covers the latest advances in gene editing and its translational applications to various diseases Written by global leaders in the fields of gene editing and stem cell therapy

Heritable human genome editing - making changes to the genetic material of eggs, sperm, or any cells that lead to their development, including the cells of early embryos, and establishing a pregnancy - raises not only scientific and medical considerations but also a host of ethical, moral, and societal issues. Human embryos whose genomes have been edited should not be used to create a pregnancy until it is established that precise genomic changes can be made reliably and without introducing undesired changes - criteria that have not yet been met, says Heritable Human Genome Editing. From an international commission of the U.S. National Academy of Medicine, U.S. National Academy of Sciences, and the U.K.'s Royal Society, the report considers potential benefits, harms, and uncertainties associated with genome editing technologies and defines a translational pathway from rigorous preclinical research to initial clinical uses, should a country decide to permit such uses. The report specifies stringent preclinical and clinical requirements for establishing safety and efficacy, and for undertaking long-term monitoring of outcomes. Extensive national and international dialogue is needed before any country decides whether to permit clinical use of this technology, according to the report, which identifies essential elements of national and international scientific governance and oversight.

CRISPR/Cas is a recently described defense system that protects bacteria and archaea against invasion by mobile genetic elements such as viruses and plasmids. A wide spectrum of distinct CRISPR/Cas systems has been identified in at least half of the available prokaryotic genomes. On-going structural and functional analyses have resulted in a far greater insight into the functions and possible applications of these systems, although many secrets remain to be discovered. In this book, experts summarize the state of the art in this exciting field.

Genome editing is a powerful new tool for making precise alterations to an organism's genetic material. Recent scientific advances have made genome editing more efficient, precise, and flexible than ever before. These advances have spurred an explosion of interest from around the globe in the possible ways in which genome editing can improve human health. The speed at which these technologies are being developed and applied has led many policymakers and stakeholders to express concern about whether appropriate systems are in place to govern these technologies and how and when the public should be engaged in these decisions. Human Genome Editing considers important questions about the human application of genome editing including: balancing potential benefits with unintended risks, governing the use of genome editing, incorporating societal values into clinical applications and policy decisions, and respecting the inevitable differences across nations and cultures that will shape how and whether to use these new technologies. This report proposes criteria for heritable germline editing, provides conclusions on the crucial need for public education and engagement, and presents 7 general principles for the governance of human genome editing.
