As shown in Figs. 8a-c, the typical microstructures, e.g., mucin-like stroma (MS, green arrows), glioblastoma multiforme (GM, blue arrows), glioma (G, orange arrows), as well as fibrous (F, yellow arrows) and vesicles (V, red arrows) could be identified clearly. This evidence concerns the gene MUC5AC and glioblastoma.
