Figure 1.

Representative dot plot of impression cytology samples.

Notes: Cell size (forward scatter pulse height [FSC-H]) versus cellular granularity (side scatter pulse height [SSC-H]) data of all events collected by cell cytology are plotted. The outlined area demonstrates a single homogenous cell subpopulation. In each sample, 1,000–10,000 cells were analyzed; samples containing less than 1,000 cells were discarded. All specimens were examined by a masked observer.
