Control and Augmentation of Long-Term Plasmid Transgene Expression In Vivo in Murine Muscle Tissue and Ex Vivo in Patient Mesenchymal Tissue

Figure 2

Duration of plasmid-based CMV promoter activity in vivo in liver and muscle. pCMV-luc was delivered to liver and thigh muscle ( 𝑛 = 1 0 ) by electroporation and luminescence analysed in vivo over time using IVIS live whole body imaging. CMV activity in liver is initially high but reduced to background level by day 14. A gross reduction in expression over time was not apparent in muscle.
