This images shows lung tissue isolated from a mouse. The orange and purple areas are the tissue containing the lung cells and the white areas is the space where air flows through during breathing. The lung cells where stained with a dye and the intensity of the staining is illustrated with the orange to purple colors.
My research focusses on a protein that is known to drive lung cancer development. I am investigating the role of differential levels of this protein throughout the tumor and how this can cause metastatic cancer progression. To correlate changes of the protein levels with malignant cancer I have to exclude that such heterogeneity also occurs in healthy lung tissue. With this image I could show that the protein is not differentially expressed in healthy lung tissue.
