Research Abstract |
The direct cause of death of cancer, which is the leading cause of death in Japanese, is metastasis. Above all, brain metastasis is developed by cancer cells' intravasating,extravasating, and proloferating in the brain. The purpose of our project was to investigate how the circulating tumor cells get into the brain, adapt to the microenvironment, and proliferate in the brain. We established highly-brain metastatic cancer cells which were expressing green fluorescent protein and succeeded in developing new system in which the brain microenvironment was reconstructed in vitro. Using the system, we clarified that different types of cancer cells showed the different ways of proliferating in the brain.
