Combined negative pressure wound therapy with open bone graft for infected wounds with bone defects: An experimental study.

Background: Bone and soft-tissue defects in infected wound have been an intractable problem to many surgical consultations. Infected wounds with bone defects are physical and financial burden to society. Nowadays, infected wounds with compound defect of bone and soft tissues are common in orthopedics department.

Early cellular responses of BMSCs genetically modified with bFGF/BMP2 co-cultured with ligament fibroblasts in a three-dimensional model in vitro.

Currently, a number of strategies including the implantation of bone marrow-derived mesenchymal stem cells (BMSCs) and growth factors have been developed to regenerate the tendon-to-bone interface after performing anterior cruciate ligament reconstruction. However, the mechanisms behind the interactions of the implanted BMSCs and tendon cells remain to be elucidated. The aim of this study was to evaluate the early cellular responses of BMSCs genetically modified with basic growth factor growth factor (bFGF)/bone morphogenic protein 2 (BMP2) and ligament fibroblasts in a three-dimensional co-culture model.
