Research Abstract

Non-irradiated fibroblasts promote the survival, self-renewal and cancer cell production of cancer stem cells under cancer stem cell-fibroblast interaction, while irradiated fibroblasts tend to promote those of the cancer stem cells. However, both fibroblast types show no significant difference between irradiated and non-irradiated fibroblasts. Finally, the irradiated fibroblasts-cancer stem cell interaction does not induce the significant change of the genomic instability marker p53-binding protein 1(53BP1) expression
