Key genetic attributes of patient derived xenographs (PDX) cell lines.

Method	Mayo Sarkaria qMS-PCR	MD Anderson CLIA qMS-PCR	Sanger Sequencing
GBM	MGMT METHYLATION	MGMT METHYLATION	TERT	IDH1	IDH2
6	U	Indeterminate	C228T	wt	wt
12	M	M	C250T	wt	wt
43	U	M	C228T	wt	wt

Cell lines used in experiments are all IDH1/2 wildtype. They have two distinct TERT mutations. U = unmethylated, M = methylated.
