Objective
The objective of this study was to investigate the histogenesis of ectomesenchymal
chondromyxoid tumors (ECTs) of the tongue.
Study Design
The biochemical characteristics of a rarely occurring tumor of the tongue were analyzed
by immunohistochemistry and reverse-transcriptase polymerase chain reaction (RT-PCR),
and its biological properties were assessed in primary culture in serum-free media.
Results
Immunohistochemistry showed that the tumor cells were strongly positive for vimentin,
S-100, and glial fibrillary acidic protein (GFAP), but negative for cytokeratin and
epithelial membrane antigen. In primary cultures, the cells derived from the ECT were
morphologically similar to neuronal cells and expressed Nanog, GFAP, and MAP2. RT-PCR
analysis of the surgical specimen was positive for OCT3/4, Sox2, Nanog, MAP2, and
CD105 mRNAs.
Conclusions
The results of the present study indicate that ECTs originate from the ectomesenchymal
cells of the neural crest and are similar in their molecular and biological characteristics
to undifferentiated mesenchymal stem cells.
