Comparison of transduction efficiency among various cell types by a lentivector containing CMV promoter

In this study, the third-passage isolated MSCs from four different species, including ovine and goat cardiac fibroblasts, HEK293T, and L929 cell line were transduced by concentrated virus particles. Then, transduction percentage was detected by flow cytometry. The findings showed different transduction efficiencies for various cells of one species or other species, indicating that differentiated and undifferentiated cells had different transduction percentages. Different degrees of transduction observed in differentiated and undifferentiated cells might be the result of various lentiviral receptors on the plasma membrane, site of integration, and activity of CMV promoter. Further, other regulatory factors involved in cell transduction and target gene expression can cause different percentages of transduction.
