This repository allows scientists to acquire cells on the basis of their GBM subtype (defined by RNAseq or methylomics) and to filter their selection on the basis of a plethora of parameters, including molecular subtype, EGFR amplification/mutation, MGMT methylation, or isocitrate dehydrogenase 1 and 2 (IDH1/2) gene status. Here, MGMT is linked to glioblastoma.
