Schematic representation of MMTV and MPMV based vectors. (A) MMTV genome, MMTV transfer vectors, and expression plasmids containing MMTV or MPMV packaging signal. (B) MPMV genome, MPMV transfer vectors, and expression plasmids containing MPMV or MMTV packaging signal. The design and construction of these vectors is described in materials and methods and can be further obtained from authors upon request. CMV, human cytomegalovirus promoter; SV, Simian virus 40 promoter; hygr, hygromycin resistance gene; CTE, constitutive transport element from Mason-Pfizer monkey virus (MPMV); EGFP, enhanced green fluorescence protein gene; BGH, bovine growth hormone.
