Effects of heme oxygenase-1-modified bone marrow mesenchymal stem cells on microcirculation and energy metabolism following liver transplantation

Figure 4 Portal vein pressure on the 7^th d after liver transplantation. A: Portal vein pressure (PVP) of normal BN rats; B: PVP of normal saline (NS) group on postoperative day (POD) 7; C: PVP of bone marrow-derived mesenchymal stem cells (BMMSCs) group on POD7; D: PVP of HO-1/BMMSCs group on POD7. PVP of both the HO-1/BMMSCs group and the BMMSCs group was significantly lower than that of NS group on POD7 (P < 0.05). HO-1/BMMSCs group vs NS group: 10.67 ± 0.35 vs 21.26 ± 0.20 (P < 0.01); BMMSCs group vs NS group: 10.95 ± 0.22 vs 21.26 ± 0.20 (P < 0.01).
