Using gene transfer of SV40 large T-antigen in neuronal precursor cells of rats, a brain tumor model was established. The PNETs were histologically indistinguishable from the human counterparts and have been used to identify new genes involved in human brain tumor carcinogenesis.<ref name="pmid8129041">{{cite journal |vauthors=Eibl RH, Kleihues P, Jat PS, Wiestler OD |title=A model for primitive neuroectodermal tumors in transgenic neural transplants harboring the SV40 large T antigen |journal=Am.
