Figure 10. — Cell death–annexin VPI of isolated lung CSCs post-PDT. Unstained cells were used to establish the cell population (a). A positive control sample was used where apoptosis was induced using hydrogen peroxide (b). Cells receiving no treatment were used as the control (c). Cells receiving PS or irradiation alone had no significant cell death with viabilities of 92.5% and 93.2%, respectively (d,e). Cells receiving PDT showed a statistically significant increase p < 0.001 (***) in early apoptosis (21%), late apoptosis (2.6%) and necrosis (9%) (f).
