From: Lung cancer stem cells and low-intensity laser irradiation: a potential future therapy?
Possible effects of low-intensity laser irradiation and photodynamic therapy (PDT) on lung cancer stem cells (CSCs). Laser stimulatory effects can (a) cause the lung CSC to differentiate into differentiated cancer cells, (b) cause the cell to undergo apoptosis, (c) cause the cell to undergo autophagy, or (d) cause the cell to become necrotic. Effects of cell-specific aptamer-PDT include (b) apoptosis, (c) autophagy, or (d) necrosis. PS, photosensitizer.
