| Outline of Final Research Achievements |
We have developed a method to isolate and proliferate primary breast cancer cells from clinical tissue samples. Using this method, we have made frozen stocks of the cells isolated from cases with high probability of familial/hereditary breast cancers.
Although isolating circulating tumor cells (CTCs) was possible, it was unfortunately difficult to propagate them. Because of that, we focused on the study using cells isolated from cancer tissues.
We have developed a method by which DNA repair activity by homologous recombination can be measured. In this method, residual DNA damage was quantified at the G2 phase using nuclear and phospho-H2AX staining.
