The present invention relates to the preparation of mesenchymal stem cells, which are for the proliferation of viral vectors and viruses, and enable virus production and release timing control such that tumor targeting can be improved and viruses can be mass-produced. In addition, the tumorigenesis of mesenchymal stem cells of the present invention can be fundamentally blocked, safety is secured by enabling virus production and release to be controlled at desired time points, and antitumor effects can be maximized.

Editing of VEGFR2 abrogated angiogenesis in two mouse models of oxygen-induced retinopathy (OIR) and laser-induced choroid neovascularization (CNV). Provided are compositions, e.g., Adeno-Associated Virus (AAV) Vectors comprising sequences encoding CRISPR/Cas9 proteins and guide RNA, and methods of use thereof for editing of Vascular endothelial growth factor receptor 2 (VEGFR2) gene to treat ocular disease associated with pathological angiogenesis, e.g., neovascular age-related macular degeneration (AMD), proliferative diabetic retinopathy (PDR) and retinopathy of prematurity (ROP).
