Outline of Final Research Achievements |
Recently, the cancer stem cell (CSC) is suggested to be resistant against therapy and recurrence. The fraction of CSCs was higher in clinically relevant radioresistant cells than in their parental cells. However, a long-term low dose fractionated radiation resulted in radioresistance of parental cells but did not increase CSCs fraction. We therefore conclude that the CSC phenotype is not involved in the acquisition of radioresistance of cancer cells.
