WDR12 and neoplasm: To further determine the expression of WDR12 in GSCs, we queried the Gene Expression Omnibus (GEO) databases GSE86237, which includes 18 GSCs and 7 bulk tumor cells (BTCs) isolated from human GBM patients (27), and GSE54791, which includes 3 stem-like tumor-propagating cells (TPCs) and their matched differentiated glioma cells (DGCs) (28).
