Consistent with these results, the flow cytometry data revealed that ZDHHC23 was exclusively co-expressed with the proneural GSC marker, CD133, in the leading edge, and ZDHHC18 was tightly associated with the mesenchymal GSC marker, CD44, in the necrotic region of GBM (Fig. 3c). Here, ZDHHC23 is linked to glioblastoma.
