| Research Abstract |
Bone marrow mesenchymal stem cells(MSCs) have pluripotent differentiation capability and are expected to be used for regenerative medicine. However, the differentiation capability decreases with their prolonged proliferation. Moreover, our previous studies showed that the such cells had not only less bone formation capability but also suppressed bone formation. In this study, we focused on EPHA5 as the suppressor candidate from microarray and co-culture study.
We achieved 5 cm long bone regeneration using MSCs in a monkey femur bone defect model. The regenerated bone proved its bone union capability that is one of the impossible characteristics of natural bone.
