Despite the different number of genes represented by each microarray platform, all of them satisfied the selection criteria, segregated properly NF and MPNST samples, and supported relevant works that identified potential biomarkers and therapeutic targets [3,10,16,17] or discriminated neurofibromas and MPNST from other mesenchymal tumors [15]. This evidence concerns the gene NFASC and mesenchymal cell neoplasm.
