简要总结

We could not enrolled patients with predetermined defect sites, therefore, we could not achieve main purpose of this clinical research. Although it is not possible to fully discuss about the efficacy of this mixture of regenerative cells based on this incompleted study, it seems to be short of number of cells in case of large defect, because no clear improvement in bone regeneration was observed in the BM-MSC group.
