Partial load-bearing rabbit ulnar segmental defects are regenerated with biocompatible grafts with or without bone marrow-derived mesenchymal stem cells

Abstract

BACKGROUND: The autologous bone grafts still have been used as the gold standard to initiate and facilitate bone healing in cases with bone defects. Because of some disadvantages of autologous bone grafts, the new biocomposite grafts have been researched. The purpose of the present study was to investigate whether the bone marrow-derived mesenchymal stem cells (BM-MSCs) loaded into a biocomposite scaffold enhance bone regeneration.
