Figure 2.
Directly applied NTP as well as NTP-treated medium induced apoptosis more effectively in 6606PDA. 6606PDA cells (left panel) or primary, murine fibroblasts (right panel) were exposed to argon gas-treated medium (control) or NTP-treated medium. After an incubation of 24 h, cells were imaged for activated caspases 3/7 by fluorescence microscopy. Representative images of two independent experiments are shown. Scale bars represent 100 µm.
