![Sensitivity of MCF-7 mammosphere CSCs to neutron radiation](https://image.oaes.cc/709cfe1e-4b16-4956-8a7e-6dea50167456/4911.fig.7.jpg)
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.
