Considering these data and immunohistochemistry staining of DMRTA2 in GBM, we focused on determining DMRTA2 co-expression with markers of stem/progenitor cells (OLIG2 [33] and NESTIN [34]), immune cells (CD45 [35]) and blood vessels (von Willebrant factor—VWF [34]). The gene discussed is OLIG2; the disease is glioblastoma.
