Moreover, testifying to the origin of NG2/CSPG4 fragments not only from pericytes within the VBM but also from glioblastoma cells in the tumour ECM, mAb 2164H5 staining was present in proliferating tumour cells, that seemed to symmetrically segregate 2164H5-reactive NG2/CSPG4 isoforms into daughter cell cytoplasmic compartments [30]. Here, CSPG4 is linked to neoplasm.
