Abstract
Background/aim: In order to determine the synergistic effects of human placental mesenchymal stem cells (PMSCs) on hematopoiesis in vivo, we compared the intrabone marrow injection (IBMI) with the conventional intravenous injection (IVI). Materials and methods: C57BL/6 recipient mice conditioned with lethal doses of irradiation were transplanted with bone marrow mononuclear cells (MNCs) and bone marrow-derived mesenchymal stem cells (BMSCs) from BALB/c mice by IBMI or IVI. NOD/SCID recipient mice conditioned with sublethal doses of irradiation were transplanted with human umbilical cord blood MNCs (UCB-MNCs) and PMSCs by IBMI or IVI. Results: The number of hematopoietic cells was significantly higher in mice transplanted with BMSCs by IBMI than in those transplanted by IVI in a murine transplantation model (BALB/c?C57BL/6). Moreover, the percentage of human hematopoietic cells in the tibiae of the NOD/SCID mice that were transplanted with PMSCs plus UCB-MNCs was higher than that in mice transplanted with UCB-MNCs alone. In addition, in mice that were transplanted with PMSCs, PMSCs injected by IBMI were more efficient than those injected by IVI. Conclusion: Our results not only elucidated the role of PMSCs in promoting hematopoiesis, but also revealed the therapeutic potential of the combination of PMSCs and IBMI in transplantation.
