The development of osteoblasts from stem cells to supplement fusion of the spine during surgery for AIS.
Surgical correction in severe cases of AIS is often hampered by insufficient autograft bone to facilitate the fusion. The development of other sources of bone generating cells would greatly enhance the surgical. Bone marrow derived stem cells were harvested from femoral reaming during total hip arthroplasty for the purpose of differentiating into osteoblasts. Stem cells were isolated from the marrow and successfully differentiated into three cell lines (osteoblasts, chondrocytes and adipocytes) to confirm multilineage potential. Osteoblasts were developed from the stem cells and demonstrated the ability to be cultured to possibly provide a source of bone generating cells to augment surgical fusions. It is anticipated that the addition of osteoblasts created from stem cells (combined with appropriate matrix) will have significant influence on the success of AIS surgery through improvement of bone fusion.
