Figure 3. Confocal imaging of stem-like (A–C) and non-stem (D–F) XPA1 pancreatic cancer cells infected with A1-R, expressing GFP, in vitro. XPA1 pancreatic cancer cell death was induced by A1-R targeting in vitro. A1-R infection was detected in both stem-like and non-stem XPA1 cells after 60 min (B and E, respectively). A1-R induced apoptosis in both stem-like and non-stem XPA1 cells (C and F, respectively). Scale bars, 20 μm. Pre, pre-infection.
