Gene editing, particularly using the CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)/Cas system, has gained importance both as a research tool in drug discovery and for drug therapy. Cambridge Healthtech Institute’s fourth annual symposium on New Frontiers in CRISPR-Based Gene Editing will bring together experts from research and clinical laboratories to talk about the recent progress in gene editing and its growing applications. However, the technology is not without limitations. What is being done to overcome some of the inherent challenges in guide RNA design, delivery and off-target effects associated with CRISPR/Cas and what are some of the alternatives being developed? Experts from pharma/biotech, academic and government labs, and technology companies will share their experiences leveraging the utility of CRISPR-based gene editing for creating cell lines and disease models, for functional in vitro, in vivo and ex vivo screening, for target and cellular pathway identification, and for therapeutic use.
