The collagen of esophagus increases in the scar tissue in the model group. (A) The HE of periscar tissue for rats in model group. (B) The HE of scar tissue for rats in model group. (C) The Masson’s trichrome staining of periscar tissue for rats in model group. (D) The Masson’s trichrome staining of scar tissue for rats in model group. (E) The Sirius red staining of periscar tissue for rats in model group. (F) The Sirius red staining of scar tissue for rats in model group. (G,H) The multiphoton microscopic imaging of periscar and scar tissue for rats in model group. (a) The morphology of tissue components (red color coded). (b) The microstructure of collagen (green color coded). (c) The merged image of (a,b). (d) The fast fourier transform analysis of collagen. (I) The esophageal constriction ratio was decreased in the model group. (J) the collagen area was increased significantly in the model group.
