An essential hurdle in advancing this treatment lies in effectively delivering CRISPR/Cas to HSCs. While various delivery formats exist, Ribonucleoprotein complex (RNP) emerges as a particularly efficient option. RNP complexes offer enhanced gene editing capabilities, devoid of viral vectors, with rapid activity and minimized off-target effects. Nevertheless, novel delivery methods such as microfluidic-based techniques, filtroporation, nanoparticles, and cell-penetrating peptides are continually evolving. This study aims to provide a comprehensive review of these methods and the recent research on delivery approaches of RNP complexes to HSCs.
