Figure 6. De novo induction of K-5 expression in human α6⁺ cells.

(A) Schematic of dual-color lentiviral reporter construct containing mCherry under the control of a partial K-5 promoter and GFP driven by an RSV promoter. (B) Representative fluorescence images of mCherry (red) and GFP (green) at 4, 7, and 30 days after culture of α6⁺ cells infected with the dual-color lentiviral reporter. Also shown are phase contrast images of colonies. Scale bar=100 µm.
