Figure 1From: Immunohistochemical molecular phenotypes of gastric cancer based on SOX2 and CDX2 predict patient outcome SOX2 protein expression in gastric carcinomas, detected by immunohistochemistry. (A) Heterogeneity of SOX2 expression in gastric tumors. Within the same tumor sample, areas with high levels of SOX2 are observed (B) in close proximity to areas with lower expression levels of SOX2 (C). (D, E) SOX2 expression at the invasive front of tumors.Back to article page
