Within a month, both C918 and OCM1 grafts metastasized to the livers, and the metastasized tumor cells were either of the epithelioid phenotype for C918 or the mixed spindle-epithelioid phenotype for OCM1, as expected (Figs. 1f, g), suggesting that both spindle and epithelioid tumor cells are invasive and metastatic. This evidence concerns the gene OCM and neoplasm.
