Specifically, tumor cells in MVNTs variably express both immature neuronal markers, such as Human antigen C/Human antigen D (HuC/HuD), alpha-internexin (α-INA), and mature neuronal differentiation markers including Neuronal Nuclei (NeuN), neurofilaments, synaptophysin, and Microtubule-Associated Protein 2 (MAP2) [2,8,10]. The gene discussed is MAP2; the disease is neoplasm.
