Protection of ghrelin postconditioning on hypoxia/reoxygenation in gastric epithelial cells

Figure 6 Effects of capsazepine in ghrelin postconditioning on the expression of vanilloid receptor subtype 1 in human gastric epithelial cells induced by hypoxia/reoxygenation. Cells were grouped as follows: normoxic culture for 6 h (A), 2 h hypoxia/4 h reoxygenation (B), DMSO vehicle postconditioning (C), ghrelin postconditioning (10^-7 mol/L) (D), and capsazepine + ghrelin postconditioning (E). The expression of vanilloid receptor subtype 1 (VR1) in each group was observed by immunocytochemistry. Cells were observed for photography under a phase contrast microscope (× 400). The arrows indicate the positive cells which express VR1.
