主 题:Bone defects bone marrow bone tissue engineering mesenchymal stem cells periosteum
摘 要:Aim:Mesenchymal stem cells(MSCs)are an excellent potential source of cells for bone tissue engineering due to their excellent renewal ability and osteogenic differentiation *** study was designed to evaluate the bone formation properties of a demineralized cancellous bone scaffold seeded with MSCs,with or without periosteum,in a critical size bone defect model in ***:Rabbit culture-expanded bone marrow(BM)-MSCs were seeded onto a human demineralized cancellous bone(HDCB)*** defects measuring 15 mm in length were created in each radius.A total of 56 bone defects in 28 rabbits were randomly assigned to one of the 4 groups for scaffold implantation:Group 1:HDCB graft only;Group 2:periosteum-wrapped HDCB graft;Group 3:HDCB graft seeded with BM-MSCs and Group 4:periosteum-wrapped HDCB graft seeded with *** rabbits were sacrificed 12 weeks after surgery for gross observation,radiological assessment,histological analyses and biomechanical ***:New bone(NB)formation and bone healing were successfully achieved,both radiologically and histologically,on demineralized cancellous bone graft seeded with *** were improved when BM-MSCs were associated with ***:This study demonstrates that repair of bone defects in a rabbit model can be achieved through bone grafting using BM-MSCs,implanted on a demineralized cancellous bone *** formation of NB was optimized when combined with the preservation of periosteum at the site of injury.
