AbstractThis study aims to construct recombinant lentiviral vectors containing the human stem cell leukemia (SCL) gene and investigate their in vitro transfection efficiency in Interstitial Cells of Cajal (ICC) of guinea pig bladders. In this study, the human SCL gene was successfully cloned, and the recombinant lentivirus GV287-SCL was successfully constructed. The titer of the recombinant lentivirus was 5 × 108 TU /mL. After transfecting the ICCs with the lentiviral vector at different MOIs, the optimal MOI was determined to be 10.0, and the optimal transfection time was determined to be 3 days. The amplification product of the lentivirus transfection group was consistent with the target fragment, indicating that the SCL gene had been successfully introduced into ICCs. In conclusion, the recombinant lentiviral vector GV287-SCL was successfully constructed and transfected into the in vitro cultured ICCs. The successful expression of SCL in ICCs may provide an experimental basis for the in vivo transfection of the SCL gene.
