by University of Rochester Medical Center Fig. 1 Schematic of the Cas9 RNP delivery system. (A) Lipidoid nanoparticle (LNP)–encapsulated Cas9 RNP delivery system. PCL nanofibril (NF) that mimic the bone tissue environment were coated with mesenchymal stem cell membrane (MSCM) and were loaded with CXCL12α cytokine and LNP-coated Cas9 RNP. (B) The LNP-Cas9 RNP/MSCM-NF/CXCL12α complex can...
