Nevertheless, the brain tumors that form closer to the SVZ tend to be proneural or neural subtypes, while tumors form farther from the SVZ tend to be classical or
mesenchymal subtypes.
This study shows that
the mesenchymal subtype is the most aggressive subtype, that it has the poorest prognosis among affected patients, and that cancer stem cells isolated from
the mesenchymal subtype have significantly higher levels of the enzyme ALDH1A3 compared with the proneural subtype.

One GSC
subtype called the
mesenchymal GSC is more malignant and the most therapy - resistant, so Nakano and fellow researchers reasoned that identifying the regulatory molecules active in
mesenchymal GSCs might lead to novel and effective therapeutics.

mesenchymal stem - like
subtypes — all of which suggest more aggressive tumors — was also greater in the tumors of African American patients.
