Tissue engineering for bone defect healing: an update on a multi-component approach

Abstract

The need for an interdisciplinary approach in order to establish new therapeutic strategies for the therapy of bone defects has been acknowledged by the scientific community for many years. This awareness makes itself felt when looking at the multitude of approaches--ranging from cell-based to scaffold-based strategies and also including the use of osteogenic growth factors and genetic engineering--that are currently being combined to assess their potential to develop effective concepts for the treatment of extensive loss of osseous tissue. With a strong focus on the preclinical research in this field, the goal of this review is to give an update on the multi-component approaches that are currently being investigated in tissue engineering of bone.
