Popis: PDF file - 50K, Figure S6: Ex vivo comparison of vessel density in stroma vs tumor tissue. Using the Image Scope v7.1 regions of viable tumor were manually selected. 200�m micrometers were placed around the circumference of the tumor region perpendicular to the tumor edge. A second manually selected region was drawn around the perimeter of the micrometers. This effectively segments the entire tissue section into three regions of interest; the tumor, the edge within 200�m of the tumor and the distant stromal region. The Aperio (Vista, CA, USA) microvessel algorithm v1.0 was used with the following parameters (smoothing 2; dark threshold160; light threshold 210; regioning 6; completion 7) to identify the vascular density which was defined as the vessel area divided by total area (�m2).
