detection of neural differentiation markers such as glial fibrillary acidic protein ( gfap ) , s 100 protein ( s 100 p ) , neurofibrillary proteins and neuron-specific enolase ( nse ) greatly contributed to clarifying the histogenesis and differentiation potential of undifferentiated small-cell tumors grouped as primitive neuroectodermal tumors ( pnets ) which include cerebellar medulloblastomas and pinealoblastomas as well as neuroblastomas and ependymoblastomas .
