  1. Subjective scoring of immunoreactivity of 6 archived canine oral fibrosarcoma cases for VEGFR-2, PDGFR-α, PDGFR-β, and Kit. The estimated percentage of tumor cells displaying immunoreactivity, the predominant location(s) of staining (C = cytoplasmic, M = membranous, or N = nuclear), and the subjective intensity of staining (+, ++, or +++) are displayed along with semi-quantitative measurement of immunoreactivity using computer image analysis software and threshold-processed photomicrographs
