Determination of Tumor Cell and Stroma Percentages within a Human Pancreatic Cancer Xenograft. Hematoxylin-stained, frozen sections (original magnification, ×200) were analyzed to determine the percentage of tumor occupied by BxPC-3 cells in 5 MV-NIS-infected and 3 uninfected control tumors. The rectangle represents a known area, and regions of interest (ie, stroma [fibroblasts, collagen, etc]) were outlined manually for image analysis.
