Research Abstract |
Various types of human cultured cells, including induced pluripotent stem cells (hiPSCs), were cultured under chronic gamma-irradiation at low and middle dose-rates (10-1000 mGy/day). The cell-type specific cellular responses of these cells to irradiation and the underlying molecular mechanisms were analyzed to examine their dose-rate-dependence. A combination of chronic irradiation culture conditions and advanced high-throughput techniques, such as the next generation sequencing system and an automated image analyzing system, could reveal a variety of cellular systems for the maintenance of the genomic integrity and the molecular mechanisms of p53-dependent cellular responses.
