Site-specific integration via genome editing technologies has been implemented in Chinese hamster ovary (CHO) cells for predictable and efficient cell line development and engineering. Various strategies have been employed to enhance knock-in (KI) efficiency for precise homology-directed repair (HDR)-mediated targeted integration of transgenes in CHO cells. Given the cell cycle-dependent regulation of the DNA damage repair pathway, cell cycle synchronization to the HDR-favored S/G2 phase has been successfully utilized in mammalian
