Taking a closer view of the MPNST region, SP‐01's methylome profile matched that of melanoma (like STS‐26T, which was recently reclassified from an MPNST to a melanoma cell line [38]), tumor NF1‐08 clustered with the classic MPNST group (as for ST88‐14 and S462 cell lines), and NF1‐09 clustered in the rather catchall MPNST‐like sarcoma group (Fig. 1D, Table 1). This evidence concerns the gene NF1 and malignant peripheral nerve sheath tumor.
