CSPG4 and neoplasm: To establish the molecular identity and spatial distribution of vascular and tumour-associated NG2/CSPG4 molecules, as well as to highlight putative foetal-adult-neoplastic transitions in the patterns of PG expression, we generated a panel of 63 murine mAbs against the recombinant ectodomain of human NG2/CSPG4, that were characterized through a repertoire of immune-assays and by immunohistochemistry on tissue sections (see below).
