制备方法

hACE2 cDNA was cloned as previously described35 and inserted into the pEGFP-N1 plasmid (BD Biosciences) upstream of the SV40 polyA tract, replacing the coding sequence for enhanced green fl uorescence protein. We retrieved the mouse ACE2 promoter (9 kilobases) by digesting bacterial artifi cial chromosome (RP23-75P20) DNA with KpnI and EcoRV and inserted it upstream of the hACE2 coding sequences. After hACE2 was identifi ed in transfected NIH3T3 cells, the plasmid was linearized with KpnI and KasI and purifi ed with phenol. Fragments carrying the mouse ACE2 promoter driving the hACE2 coding sequence were introduced by microinjection into the pronuclei of fertilized ova from ICR mice. The injected zygotes then were transplanted into the oviducts of pseudopregnant mice. Mice in which the transgene integrated were identifi ed from tail biopsies. These mice were bred to produce offspring for analysis.
