Radiosensitivity of hepatocarcinoma cell line BEL-7402.
OBJECTIVE: To assess the radiosensitivity of human hepatocarcinoma cell line BEL-7402. METHODS: Human hepatocarcinoma cell line BEL-7402 was cultured in vitro and then subjected to exposure to 6 MV X-ray at the doses ranging from 0 to 10 Gy. The survival rate of the cells following the exposure was assessed by determining the colony-forming units during further cell culture 12 to 14 d after the exposure, and the parameters for the radiosensitivity calculated. RESULTS and CONCLUSION: The parameters of BEL-7402 cells (D0=1.6, Dq=1.3, n=2, 4, SF2=0.63+/-0.05 Gy) demonstrates a high sensitivity of the cells to radiation.
