Figure 2

Typical redox images and corresponding histograms of indolent human breast tumor MCF-7 mouse xenografts (tissue section depth 980 μm). The x axes of the histograms represent the Fp or NADH redox ratio or nominal concentration. The y axes represent the number of pixels in the tumor section having a specific value of Fp or NADH redox ratio or nominal concentration. The small round spots outside the tumor section are Fp or NADH reference standards. The image matrix was 128×128, and the step size was 200 μm (twice that of the pixel size of MDA-MB-231 xenograft images in Fig. 1).
