In order to study the changes of micronuclei cell frequency in the non-immune cell types, the human intestinal crypt epithelial cell (HIEC) was treated by CpG-ODN after radiation. MTT assay and micronuclei assay were used in this research. The result of MTT assay shows that CpG-ODN does not have any toxicity to HIEC in the concentration range of 0.00–1.25 μmol/L. Micronuclei assay measurement indicates that CpG-ODN can protect HIEC from radiation damage by reducing the micronucleus frequency (MNF) and the micronucleus cell frequency (MNCF). The experiment results reveal that CpG-ODN is safe and may have radioprotection effect on some non-immune human cell types.
