Ginger Oleoresin Alleviated γ-Ray Irradiation-Induced Reactive Oxygen Species via the Nrf2 Protective Response in Human Mesenchymal Stem Cells

Figure 3

Ginger oleoresin reduced the IR-induced DNA strand breaks in hMSCs. The levels of DNA strand breaks were assayed by comet assay. (a) Representative micrographs—(A): untreated group; (B): treated with ginger oleoresin only; (C): treated with IR only; and (D): pretreated with ginger oleoresin and then with IR. (b) Tail DNA%. (c) Tail length. (d) Tail moment. Results are expressed as mean ± SD (). IR versus untreated control (Ctrl). ^# ginger oleoresin + IR versus IR.
