Bone tissue engineering scaffolds with HUVECs/hBMSCs cocultured on 3D-printed composite bioactive ceramic scaffolds promoted osteogenesis/angiogenesis

Abstract

The fabricated 3D-printed bioactive ceramic scaffolds could provide mechanical, biodegradable and bioadaptive support for personalized bone regeneration. In addition, the bone tissue engineering scaffolds exhibited the ability to promote osteogenesis/angiogenesis without the addition of exogenous growth factors, thus mitigating safety risks. Although application of the HUVECs/hBMSCs coculture system might be a time-consuming process, further development of cord blood storage could be beneficial for multicell coculture.
