We found that the down-regulation of the ZEB1 expression in the CD44+CD117+CSCs indeed had the similar effects as the miR-200c overexpression in the CD44+CD117+CSCs; this was reflected in the significant suppression of the tumorigenesis and tumor metastasis in the mice injected with the shZEB1 CD44+CD117+CSCs in comparison with the mice injected with the CD44+CD117+CSCs or with the CD44+CD117+CSCs with lentivirus mock. Here, KIT is linked to neoplasm.
