While rhabdomyosarcoma cell lines (Figure 3a and Figure S2) and tumor cell lines of neurogenic origin (Figure 3b and Figure S3) showed primarily centrosomal and rarely weak nuclear (indicated by asterisks) localization of NANOG, strong NANOG expression was observed both in the cell nucleus (indicated by asterisks) and at the centrosomes of the control NTERA-2 cell line (Figure 3c and Figure S4). The gene discussed is NANOG; the disease is neoplasm.
