Cell radioresistance enhanced in 3D culture system A The colonies formed by CNE-1 cells cultured in 2D, On-Surface 3D, and Embedded 3D group after different doses of X-ray irradiation. B The plating efficiency and D surviving fraction of CNE-1 cells cultured in the three culture systems after receiving different doses of X-ray irradiation (n = 3, *P < 0.05). C, E Comparison of the colony diameters under different X-ray doses in the three systems (*P < 0.05)
