Silencing of thrombospondin-1 prevents abdominal adhesion formation by reducing inflammation and oxidative stress

Figure 4 Thrombospondin-1 deficiency promotes peritoneal mesothelial cell repair (five groups, n = 5 mice/group). A: Typical picture of CK19 immunohistochemistry staining in different groups. The black arrow indicates the adhesion tissue or normal peritoneal tissues; B: Typical images of Sirius red staining in different groups, the area between the black arrows indicates adhesive tissue; C: Fiber thickness in different groups as assessed by Sirius red staining. NC: Negative control; Thbs-1: Thrombospondin-1; NS: Normal saline; LSKL: Leu-Ser-Lys-Leu.
