Over three-quarters of all craniofacial defects observed in the US per year are cleft palates. Usually involving significant bony defects in both the hard palate and alveolar process of the maxilla, repair of these defects is typically performed surgically using autologous bone grafts taken from appropriate sites (i.e., iliac crest). However, surgical intervention is not without its complications. As such, the reconstructive surgeon has turned to the scientist and engineer for help. In this review, the application of the field of tissue engineering to craniofacial defects (e.g., cleft palates) is discussed. Specifically the use of adult stem cells, such as mesenchymal stem cells from bone marrow and Adipose-derived Stem Cells (ASCs) in combination with currently available biomaterials is presented in the context of healing craniofacial defects like the cleft palate. Finally, future directions with regards to the use of ASCs in craniofacial repair are discussed, including possible scaffold-driven and gene-driven approaches.
