| Research Abstract |
We had a plan to isolate putative cancer stem cells from mouse neuroblastoma cell lines. And also we would isolate mouse neural stem cells from mouse embryonal and adult brain. Following the isolation of both stem cells, we would find the similarity and the difference between neuroblastoma cancer stem cells and neural stem cells. We have isolated mouse neural stem cells. However, we have failed to isolate neuroblastoma cancer stem cells using the sorting method by the specific cell surface marker or the neurosphere method. We suggest that after frequent passages, cancer cell lines could lose the cancer stem cells, which can be found in human primary tumor.
