Final Abstract Number: 1235
Cellectis presents the development of a novel gene editing process, leveraging the TALEN technology and non-viral DNA template delivery, enabling highly efficient gene correction and gene insertion in hematopoietic stem and progenitor cells (HSPCs).
Title: Intron Editing of HSPC Enables Lineage-Specific Expression of Therapeutics
Presenter: Julien Valton, Ph.D., Vice President Gene Therapy at Cellectis
Session Date/Time: May 5, 2024 at 12PM ET
Session Title: Gene Targeting and Gene Correction New Technologies
Presentation Room: Exhibit Hall
Final Abstract Number: 721
Gene therapy using hematopoietic and progenitor stem cells (HSPC) has the potential to provide a lifelong supply of genetically encoded therapeutics. Gene editing strategies enabling supra-endogenous expression of therapeutics often rely on constitutive promoters resulting in transgene overexpression irrespective of cellular differentiation, which could be detrimental for HSPC function. Cellectis presents the development of a TALEN mediated promoter-less intron editing strategy that relies on the endogenous cellular RNA splicing machinery to induce lineage-specific transgene expression exclusively after HSPC differentiation.
