Abstract:

BACKGROUND: Allogeneic bone marrow stromal stem cell transplantation for treatment of bone diseases is a hot topic. To seek effective methods for prevention of post-transplantation immune rejection is urgent to be solved.
OBJECTIVE: To explore the expression of MHC antigen on the surface of bone marrow stromal stem cells after osteogenic induction in vitro.
METHODS: Bone marrow samples were extracted from rabbits to in vitro isolate and culture bone marrow stromal stem cells. Then, the cells were cultured in IMDM medium containing bone morphogenetic protein-2. Flow cytometry was used to analyze the expression of MHC antigen on the osteoblasts differentiated from bone marrow stromal stem cells.
RESULTS AND CONCLUSION: There was highly expressed MHC I antigen but no MHCII antigen on the osteoblasts differentiated from bone marrow stromal stem cells. After osteogenic induction, no immune rejection was found. These findings indicate that allogeneic or xenogeneic bone marrow stromal cell transplantation can be used in the treatment of bone defects.
