Overview
This video protocol demonstrates the identification and isolation of slow dividing cells in human glioblastoma using carboxyfluorescein succinimidyl ester (CFSE). The protocol outlines the process of growing glioblastoma tumor cells, dissociating them into single cells, and utilizing flow cytometry to sort cells based on their division rates.

What is CFSE used for?
CFSE is used to track cell division and identify different sub-populations of cells based on their division rates.
How are glioblastoma cells cultured in this protocol?
Glioblastoma cells are cultured using the neurosphere assay, which allows for the growth of tumor cells in a three-dimensional environment.
What technique is used to sort the cells?
Flow cytometry is used to sort the cells based on fluorescence intensity, which correlates with cell division rates.
Why is it important to study cell division in glioblastoma?
Studying cell division can provide insights into tumor behavior and help develop more effective treatment strategies.
What are the implications of identifying slow dividing cells?
Identifying slow dividing cells can help in understanding tumor heterogeneity and resistance to therapies.
Can this method be applied to other types of cancer?
Yes, the CFSE staining and flow cytometry method can potentially be adapted for use in other cancer types to study cell division.
