Figure 1From: Effective in vivo and ex vivogene transfer to intestinal mucosa by VSV-G-pseudotyped lentiviral vectors Lentiviral vector (LV) constructs and ex vivo explant culture system. (A) Schematic representation of self-inactivating vectors containing a central polypurine tract (cPPT)/central termination sequence, immediate early cytomegalovirus (CMV) promoter. Vectors were constructed for expression of beta-galactosidase (β-Gal) and firefly luciferase (fLuc).Back to article page
