Immunohistochemical analysis of B3GNT3 in human neuroblastoma (NB) cells. (a) B3GNT3 expression in ganglioneuroblastoma (GNB), differentiating NB (DNB), poorly differentiated NB (PDNB) and undifferentiated NB (UNB). The arrows in GNB, DNB and PDNB indicate positive staining of neuroblastic cells in various states of differentiation. The UNB shows negative staining. Scale bar = 100 μm. Original magnification, ×400. (b) Percentage distribution of B3GNT3 expression in tumors with UNB, PDNB, DNB or GNB histology.
