Figure 4. The SP-C promoter mediates cell-specific DNA nuclear import in alveolar epithelial cells.

Figure 4

A. A549 cells were cytoplasmically injected with plasmids containing the indicated promoters. Eight hours later, the location of the DNA was detected by in situ hybridization (green). Between 500 and 1000 cells were injected and analyzed for each DNA. B. Plasmids containing the SPC promoter were injected into the cytoplasm of the indicated cells and 8 hours later, the location of the DNA was detected by in situ hybridization (green). Between 300 and 500 cells of each type were injected and analyzed (Degiulio et al., 2010).
