title: Characterization and chemosensitivity of two human malignant peripheral nerve sheath tumour cell lines derived from a patient with neurofibromatosis type 1.
abstract: Two new cell lines, designated NMS-2 and NMS-2PC, were established in vitro from a malignant peripheral nerve sheath tumour (MPNST) in the right thigh and a retroperitoneal lesion of a 30-year-old man with neurofibromatosis type 1 (NF1). The NMS-2 cell line was derived from the first tumour, and the NMS-2PC cell line from a retroperitoneal metastatic tumour detected 9 months later. Cultured NMS-2 cells showed epithelioid features, while NMS-2PC cells showed fibroblast-like features. However, both cell lines were strongly positive for S-100 protein. The transplanted NMS-2 and NMS-2PC tumours showed the same histological features typical of MPNST. Chromosomal analysis revealed that only the NMS-2 cells had a t (1;2) chromosomal translocation. Chemosensitivity tests demonstrated that NMS-2PC cells were far more sensitive than NMS-2 cells to Adriamycin and etoposide, which had been used clinically. All-trans-retinoic acid induced a morphological change in NMS-2PC cells so that they were no longer fibroblast-like, but epithelioid cells. We believe the epitheloid components in the MPNST were derived from typical spindle cells.
