At this age with tumor necrosis, 1st choice should be GBM, sometimes, more immunostaining just making you more confusion,
Like this oligo2 marker, some paper mentioned it is a stem cell marker, due to its non-specific, not widely use yet, that may be
the reason it is called oligo 2 but not oligo 1. Remember, any glial tumor may have intrapped neurons and oligo cells in the tumor, you do more
staining, making you harder to make a dx.
good good study, day day up.
happy new horse year.
