Figure 2From: Expression of natriuretic peptide receptor-A in esophageal squamous cell carcinomas and the relationship with tumor invasion and migrationImmunohistochemical staining for natriuretic peptide receptor-A (NPRA) in esophageal squamous cell carcinoma (ESCC) tissues and non-cancerous tissues. (A) Strongly positive staining in a primary ESCC (magnification × 200), (B) Strongly positive staining in a primary ESCC (magnification × 400), (C) negative staining in non-cancerous tissues (magnification × 200), (D) negative staining in negative control group (magnification × 200).Back to article page
