Our group has previously reported the expression of GAGE and MAGE cancer antigens in tumorigenic telomerized hMSC‐TERT20 cells.33 However, the hMSC‐TERT employed in the current study are not tumorigenic, suggesting that telomerization per se may be associated with upregulation of this gene set, forming a possible “telomerization signature.” This evidence concerns the gene TERT and cancer.
