A highly detailed, abstract-looking microscopy image filled with tightly packed, irregular cell-like shapes. The scene is dominated by bright orange and blue outlines, with green streaks and patches weaving through the tissue, plus many small pink and purple clusters scattered throughout. The background is mostly black, which makes the fluorescent colors stand out strongly. Information about the image: To develop novel strategies targeting the tumor microenvironment in lung adenocarcinoma, the TME was stained for cell type specific markers and imaged on an Axioscan 7 Slidescanner.
