FIG. 2.

Scoring system of TMA imaging selection, and examples of specificity staining Score 3. Images with blood vessels were scored on a scale of 0–3 based on the following parameters: 3: specific positive staining of blood vessel walls; 2: positive staining of other kinds of tissue other than blood vessels AND blood vessel walls have stronger staining than other kinds of tissues; 1: positive staining of more than two kinds of tissues on the slide OR has at least one other tissue stained darker than blood vessel walls; 0: poor images; very little staining of blood vessel walls (A). Examples of specific and consistent staining within blood vessel walls (B–D). Magnified of the positive staining image was shown in gray dotted squares on lower right of each image.
