成骨的

BACKGROUND: In bone tissue engineering researches, we are confronted with a problem of how to rapidly vascularization in the transition from experiments in vitro to osteogenesis in vivo. Only early establishment of blood supply can maintain the osteogenetic advantage of tissue-engineered bone.
