In contrast, differentially expressed genes between CECs isolated using the cmHsp70.1 mAb- versus EpCAM mAb-based approach, such as ROCK2 [29], STAT3 [30] and CD82, are related to EMT, stemness and endometrial cell proliferation [31] (Table 2), which are regulated via up-regulated CD44/STAT3 signaling in tumor cells [32]. This evidence concerns the gene CD44 and neoplasm.
