摘要： beta-Hemoglobinopathies are hereditary diseases originating from mutations in the hemoglobin beta (HBB) gene. Allogeneic transplantation of hematopoietic stem cells (HSCs) is the only approved treatment to date providing a cure, which is limited due to low histocompatibility from potential donors. Although several clinical trials are introducing the functional HBB gene into autologous HSCs, the ex vivo viral transfection method raises safety concerns for clinical translation. Here, we reported a novel strategy that features direct bone marrow delivery of a CRISPR/Cas9-mediated knock-in system that integrates a copy of the functional HBB gene to the genome by supramolecular nanoparticle (SMNP) nonviral vectors. We demonstrated the feasibility of SMNP vectors for the delivery of the knock-in system. First, the biodistribution of SMNPs was monitored after intraosseous (i.o.) injection in a mouse model. Second, the in vitro CRISPR/Cas9-mediated knock-in of the HBB/GFP gene via SMNP vectors was evaluated in mouse stem cells. Finally, in vivo CRISPR/ Cas9-mediated knock-in of mouse hematopoietic stem and progenitor cells (HSPCs) was performed by i.o. injection of SMNP vectors into mouse bone marrow. We believe this strategy presents a unique and in-novative approach to treating beta-hemoglobinopathies.(c) 2022 Published by Elsevier Ltd.
