Tongxie Yaofang enhances the homing efficiency of exogenous bone marrow-derived mesenchymal stem cells to the colonic mucosa and alleviates ulcerative colitis

Figure 6 Tongxie Yaofang enhances the homing of bone marrow-derived mesenchymal stem cells to the rat colonic mucosa. A: Representative images showing GFP-labeled bone marrow-derived mesenchymal stem cells in rat colon tissue; B: Quantification of GFP-labeled bone marrow-derived mesenchymal stem cells in colonic tissue. Data are presented as mean ± SD, n = 8 rats per group. ^aP < 0.001, compared with the bone marrow-derived mesenchymal stem cells group; ^bP < 0.001, compared with the Tongxie Yaofang + bone marrow-derived mesenchymal stem cells group; ^cP < 0.001, compared with the stromal cell-derived factor-1 + bone marrow-derived mesenchymal stem cells group. CON: Control group; DSS: Dextran sulfate sodium; BMSCs: Bone marrow-derived mesenchymal stem cells; TXYF: Tongxie Yaofang; SDF-1: Stromal cell-derived factor-1.
