Example texts for materials and methods:
Images were captured using a high throughput Leica SCN400 Slide Scanner automated digital image system from Leica Microsystems. Whole slides were imaged at 20X magnification to a resolution of 0.5 µm/pixel. Tissue cores were mapped using Ariol Review software. The numbers of positive (brown) and negative (blue) nuclei were determined by analysis of the high-resolution images in the Ariol software.
Immunostained tissue microarray slides were imaged on a Leica SCN400 Slide Scanner (Leica Biosystems). Tissue cores were imaged at 20X magnification to a resolution of 0.5 μm/pixel. Cells were identified utilizing standard Ariol analysis scripts. (Leica) Upper and lower thresholds for color, saturation, intensity, size, roundness, and axis length were set for both blue Hematoxylin staining of nuclei and for brown DAB reaction products. Thus, brown (DAB) positive cells can be distinguished from blue (Hematoxylin only) negative cells. The area of positive staining per core was calculated as a percent of the total analyzed area divided by area of brown (DAB-positive) pixels.
Fluorescent, immunostained tissue slides were imaged on an Aperio Versa 200 automated slide scanner (Leica Biosystems). Tissue cores were imaged at 20X magnification to a resolution of 0.323 µm/pixel...
