Effect of CXCR3/HO-1 genes modified bone marrow mesenchymal stem cells on small bowel transplant rejection

Figure 1 Identification of bone marrow-derived cells as bone marrow mesenchymal stem cells. Morphology of first-passage (A) and third-passage (B) BMMSCs (× 100). The differentiation capability of BMMSCs into adipogenic or osteogenic cells was evaluated by oil red O (× 200) (C) or Von Kossa staining (D) (× 200). The arrows indicate the red lipid droplets (C) or the black calcium deposition (D); The proportion of CD29-positive and CD34-negative cells was 99.8% (E); The proportion of CD90-positive and CD45-negative cells was approximately 98.9% (F); The proportion of RT1A-positive and RT1B-negative cells was 98.6% (G). BMMSCs: Bone marrow mesenchymal stem cells.
