Fig. 3

CTCs collection and enrichment phase. The figure reports CK20 (down dot plots) and Fibronectin (up dot plots) expression (x-axis, logarithmic scale) on side scatter-height (SSC-H, y-axis, logarithmic scale) collected from two different gradient density phases corresponding to the mononuclear cell layer (red line) and CTC phase (blue line) respectively. Central histogram shows the overlay CK20 expression (x-axis, logarithmic scale) on CTCs (y-axis, percentage) of the two different density ranges
