Ginger oleoresin increased the cell viability and reduced the γ-ray irradiation-induced ROS level in hMSCs. Cell viability was measured using the MTT assay (a). The level of ROS was measured using DCF fluorescence with a fluorescence microscope (b) and flow cytometry (c). Cells were untreated (Ctrl) or treated with ginger oleoresin (10⁻⁴ g/mL) (Trt) and γ-ray irradiation (4 Gy) (IR) or pretreated with ginger oleoresin (10⁻⁴ g/mL) and then γ-ray irradiation (4 Gy) (Trt + IR). Results are expressed as mean ± SD (n = 4). ^∗p < 0.05 IR versus untreated control (Ctrl). ^#p < 0.05 Trt + IR versus IR.
