Gene expression profiling of gastric cancer by microarray combined with laser capture microdissection

Figure 1 A representative example demonstrating precisely procurement of target cells from admixture of different cells by laser capture microdissection (Hematoxylin & eosin staining, X 100) (A, B, C, D).

Figure 2 A representative example of increased expression of trefoil factor 1 in a patient with intestinal type gastric cancer (immunohistochemical staining, X 100).
