NANOG and neoplasm: NANOG was highly expressed in the miR-135b-5p-high group within clusters 1 and 14, and elevated expression of C-MYC and CD24 was observed in the miR-135b-5p-high group within cluster 14, indicating a more remarkable stemness property of tumor cells in HCC with high miR-135b-5p expression (Figure 3(e)) [30].
