Protective effect of bone marrow mesenchymal stem cells in intestinal barrier permeability after heterotopic intestinal transplantation

Figure 1 Morphology and flow cytometry results of Lewis-derived bone marrow mesenchymal stem cells. A: First-passage bone marrow mesenchymal stem cells (BM MSCs); B: Second-passage BM MSCs; C: Third-passage BM MSCs (× 200 magnification); D: The proportion of CD90⁺ and CD450^- cells was approximately 95.48%; E: The proportion of CD29⁺ and CD34^- cells was approximately 99.82%; F: The proportion of RT1A⁺ and RT1B^- cells was approximately 99.87%.
