The tumor tissues displayed an enriched expression of transcription factors (e.g., Dlx2, Gbx2, Foxb1, and Nkx2.2) critical for brain development, tanycyte markers (e.g., Ptprz1, Fabp7, Crym, and Gja1), and differentiation markers (e.g., Dcx, Olig1, and Cspg5) (Fig. 7d). This evidence concerns the gene CSPG5 and neoplasm.
