Structure of an expression vector for the Pdx1-Venus cDNA. A schematic presentation of the Pdx1-Venus transgene used to generate transgenic pigs. The fusion gene (8.4 kb) consists of 6.5 kb of the mouse Pdx1 promoter and a rabbit β-globin gene including an insertion of 0.72 kb Venus cDNA in the 3rd exon and a polyadenylation signal in the 3′ –flanking region. Transcription and translation start site are indicated by +1 and M, respectively.
