Expression of α-SMA in EGFP⁺ cells migrating into the fibrotic liver. (A) EGFP as green. (B) α-SMA as red. (C,D) Merged images of EGFP, Cy3-labeled α-SMA, and TO-PRO-3. White asterisks indicate cells expressing both EGFP and α-SMA. Bars equal 30 μm. Images were acquired and processed as in Figure 2A.
