Outline of Final Research Achievements |
Cancer stem cells (CSC) or matured cancer cells were fractionated from cancer cell lines. Tumor endothelial cells (TEC) were separated from transplanted tumors in vivo model. CSC were co-cultured with TEC or treated with TEC conditioned media (TEC-TM). These experiments revealed that activation of survival signal such as Akt or NF-kB, alteration of expression levels of CSC markers and inhibitory effect against apopotosis were induced in CSC. Furthermore, co-cultivation of CSC with TEC separated from highly metastatic tumor induce the formation of large sphenoid or inhibitory effect for anoikis by TEC.
