EP4 agonist alleviates indomethacin-induced gastric lesions and promotes chronic gastric ulcer healing

Figure 5 EP4 agonist promoted gastric ulcer healing in mice. Mice with gastric ulcers were treated with vehicle or EP4 agonist from day 3 to day 10 post-surgery. Gastric ulcers were assessed on day 7 or 11, respectively. A is quantification of ulcer sizes under dissection microscopy with 16 × magnification, ^bP = 0.003, n = 16; B is representative images of gastric ulcers; the macroscopy images are at original magnification, × 16; the microscopy images are at original magnification, × 40 from slide sections.
