H&E staining of mouse lungs following in vivo minicircle and plasmid DNA transfections.
H&E stained CD1 mice lung sections following oropharyngeal instillations of (a) water as a vehicle control, LED-1 vectors containing (b) pMC.Luc2, (c) MC.Luc2 at an equal mass to pMC.Luc2 and (d) MC.Luc2 equimolar to pMC.Luc2. Scale bars are 100 μm.
