Given that we had deliberately focused on molecules already connected to glioblastoma stemness in the literature, it seems legitimate to regard the CD44+/CD133+/ITGA6+/CD36+ signature as “stemness‐associated.” All markers had already individually been described as stemness‐related,29, 30, 31, 33 which is why they were chosen. This evidence concerns the gene ITGA6 and glioblastoma.
