Effects of Cbfa1 on osteoanagenesis during avascular necrosis of femoral head
We observed the effect of Cbfa1 on bone regeneration and microvessel density (MVD) in the process of avascular necrosis of femoral head (ANFH). Imageology and morphology were taken to verify the success of the ANFH models. Meanwhile, real-time PCR was performed to observe the dynamic expression of Cbfa1. The surface cartilage of the femoral head and the subchondral bone began to degenerate since 4 weeks post-operation;...
