Clonality analysis of neuroendocrine cells in gastric adenocarcinoma

Figure 1 Chromogranin A expression in gastric cancer (× 100).

Figure 2 Images shown before and after laser-capture microdissection (× 200). A: Before laser-capture microdissection (LCM); B: After LCM.

Figure 3 Examples of microsatellite instability and loss of heterozygosity in gastric cancer examined by single-strand conformation polymorphism analysis. NE: Neuroendocrine; T: Tumor samples; N: Normal tissue controls; MSI: Microsatellite instability; LOH: Loss of heterozygosity. Arrows show the increasing and missing of alleles.
