Figure 7. (A) Dose dependence of the CA of CSCs in mammosphere culture for γ-radiation (Curve 1) and γ,n-radiation (Curve 2). (B) Dose dependence of the RBE of γ,n-radiation assessed by the CA of the mammosphere cells. Experiments were repeated five times. CA: clonogenic activity; CSCs: Cancer stem cells; RBE: relative biological effectiveness.
