I have posted a summary snip-it. It should be the first comment-post. Basically the paper provides evidence that most sex-linked, X-chromosome, cerebral brain tumors (also referred as astroblastomas) are from the same cell type in fetal development. With this cell origin and gene types known possible drug therapeutics can be made targeting these cells in juvenile and possibly young adult brains. Most brain tumors of cerebral origin have to be removed surgically as drug therapeutics are non-existent.

Glial cells are the support cells of neurons in the brain, so gliomas are the cells that are the tumors and there are several types of glial cells but to group all brain tumor types you can call them astroblastomas.
