Gene expression signatures of the PRMS tumors.

Several groups identified CSCs in solid tumors, including breast, brain, thyroid, melanoma, colon, pancreatic, liver, prostate, lung, head and neck, ovarian, and stomach cancers, by adopting many biomarkers. Here, we examined PRMS by gene expression microarray analysis for them. As a result, the tumor expressed various specific genes in each CSCs, SCs, FAPs, and PICs. Gene expression of the tumors by subcutaneous injection of the PRMS cell line, RMS3.
