We found that the CD68+ cell percentage in miR-454-depleted PANC-1-cell-formed tumor was significantly higher than control, while the CD68+ cell percentage in miR-454-overexpressing PANC-1-cell-formed tumor was significantly lower than control, shown by representative flow charts (Fig. 4A), and by quantification (Fig. 4B). Here, CD68 is linked to neoplasm.
