Assessment of Control Tissue for Gene and Protein Expression Studies: A Comparison of Three Alternative Lung Sources
Figure 3
Representative immunohistochemical staining in the bronchial and alveolar lining and macrophages. The level of VEGFA expression was diminished in the bronchial lining of cancer resection (a) compared to transplant biopsy (b) and pneumothorax (c). The alveolar lining shows elevated levels of VEGFA in pneumothorax (f) compared to cancer resection (d) and transplant biopsy (e). The level of PGF expression was diminished in macrophage infiltrate in lung cancer (g) compared to transplant biopsy (h) and pneumothorax (i). Magnification 250x.
