Figure Lengend Snippet: Immunostaining of canine and human histiocytic sarcoma (HS) for osteopontin. Formalin-fixed paraffin-embedded tissues from 18 canine HS and five human HS were stained for osteopontin expression. Slides scanned using an Aperio AT2 automated slide scanner (Leica Biosystems) were visualized using ImageScope software (Leica Biosystems) and an algorithm for quantifying positive pixels was applied to non-necrotic areas of the entirety of the outlined tumor area. Photomicrographs of representative canine HS with primary tissue of origin of A lymph node (LN), B lung, C peri-articular (PA) tissues and D spleen. E Quantification of osteopontin staining grouped by anatomic location in 18 canine HS samples. Each dot represents an individual tumor, and the bar represents the anatomic mean. Photomicrographs of human tumors from five patients diagnosed with HS in F the brain, G subcutaneous tissue of the buttock, H subcutaneous tissue of the foot, I spleen and J tonsil. K Quantification of osteopontin staining grouped by species. Each dot represents an individual tumor, and the bar represents the species mean. Scale bars measure 200 μm
