[Huge thoracic wall defect repaired by tissue engineered bone transplantation].
OBJECTIVE
A rare huge desmoplastic fibroma on thoracic wall in 1 female case of 25 years old was resected, and the accompanying huge thoracic wall defect, ribs and soft tissues were repaired by tissue engineered bone and pedicled flap. The paper aims to explore the clinical results of early stage after operation.


METHODS
Autogeneic bone marrow stromal cells (MSC) were obtained from bone marrow puncture of iliac bone and isolated and cultured according to the Houghton's methods, MSC were directively induced and differentiated to osteoblasts. Allogeneic ribs were made to the bio-derived bone scaffold materials after treatment of decell, deantigen, decalcification and dry freezing. 5 x 10(6)/ml MSC were cocultured with the bio-derived bone for 6 days in vitro. After intact resection of tumor, the diaphragm flap was applied to repair pleural cavity, the three defect ribs were repaired by tissue engineered bone and the soft tissue defect was repaired by transfer of pedicled ipsilateral abdominal flaps.


RESULTS
The patient recovered well with first intention. Followed up for 3 months, tissue engineered ribs were matured in vitro and the heart and pulmonary functions were improved markedly.


CONCLUSIONS
The tissue engineered bone constructed by autogeneic MSC is advantageous in individual treatment.
