Figure 2.
Wound fluids collected from patients who underwent surgery only (WF) had a stronger effect on ALDH1 activity compared with wound fluids harvested after the intraoperative electron radiotherapy procedure (RT-WF). The stimulatory effect was dependent on the histological subtypes of the cell lines. Columns represent the mean of 6–8 randomly selected WF and RT-WF. The control was harvested from medium supplemented with 10% fetal bovine serum only. Bars represent the standard deviation. Statistical analyses were conducted using Student's t-test. *P≤0.05. ALDH1, aldehyde dehydrogenase 1; CTR, control.
