27th American Society of Gene and Cell Therapy Annual Meeting

May 07, 2024 ‐ May 11, 2024 in Baltimore, Maryland

Back to all events

ASGCT 2024 will be held in Baltimore, Maryland on May 7-11, 2024

Cellectis will present two posters :

Title: Circularization of Non-Viral Single-Strand DNA Template for Gene Correction and Gene Insertion Improves Editing Outcomes in HSPCs

Presenter: Alex Boyne, Gene Editing Platform Manager at Cellectis

Session Date/Time: May 9, 2024 at 12PM ET
Session Title: Nonviral Therapeutic Gene Delivery and Synthetic/Molecular Conjugates
Presentation Room: Exhibit Hall
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 8, 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.
