Glioma stem cells are a specific type of glioma cell population in glioma tumors that have neural stem cell-like features. These cells closely mimic the genotype, gene expression profile, and biology of their parental primary tumors (Lee et al., 2006).
Features:
- Ability to Self-renewal
- Expression of neural stem cell markers
- Resistance to radiation
Niche for glioma stem cells:
Glioma stem cells require a special environment that helps GSC to maintain its stem cell-like properties. Such an environment is provided by Niche, a specific region where GSCs are likely to reside.
A perivascular niche has been described for Glioma stem cells (Calabrese et al., 2007).
Significance:
GBM recurrence is linked to GSC by many reports.
