Abstract (original English)
Extracellular vesicles (EVs) have been investigated due to their natural biocompatibility and targeting capabilities. The specific approach of combining EVs with liposomes to create hybrid nanoparticles (ELNPs) for the delivery of the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas9) system for deletion of the HGF gene in stem cells, but their effectiveness in encapsulating large nucleic acids is limited due to their small size. This study aimed to knock out the HGF gene by the CRISPR/Cas9 system by ELNPs, and it was expected that the efficiency of the CRISPR/Cas9 system transfer would increase compared to the usual methods of using lipofectamine in stem cells from apical papilla (SCAPs). In this study, gRNA suitable for the HGF gene is designed first, and after insertion into the CRISPR/Cas9 vector, it enters Lipofectamine 2000. In the next step, ELNPs are prepared after collecting EVs and hybridizing them with liposomes containing CRISPR/Cas9 vector. Then, these integrated nanoparticles were presented to SCAPs, and the removal of HGF gene expression was evaluated at the level of RNA and protein. This study showed that the CRISPR/Cas9 system can be efficiently transferred to SCAP cells using ELNPs. Genomic DNA sequencing analyses of SCAP cells showed a unique pattern of mutation, highly likely mediated through EVs. Quantitative
