Figure 7 Number of tumor necrosis factor-α-, interleukin-1β-, and monocyte chemotactic protein-1-producing cells in interstitial space of ulcer scar site in patients with gastric ulcer whose ulcer healed with flat vs non-flat pattern assessed by chromoendoscopy. n = 6, ^bP < 0.01 vs flat group. TNF-α: Tumor necrosis factor α; IL-1β: Interleukin-1β; MCP-1: Monocyte chemotactic protein-1.
