The Use of Bone Marrow Stromal Cells (Bone Marrow-Derived Multipotent Mesenchymal Stromal Cells) for Alveolar Bone Tissue Engineering: Basic Science to Clinical Translation
Access this Article
Bone tissue engineering is a promising field of regenerative medicine in which cultured cells, scaffolds, and osteogenic inductive signals are used to regenerate bone. Human bone marrow stromal cells (BMSCs) are the most commonly used cell source for bone tissue engineering. Although it is known that cell culture and induction protocols significantly affect the in vivo bone forming ability of BMSCs, the responsible factors of clinical outcome are poorly understood. The results from recent studies using human BMSCs have shown that factors such as passage number and length of osteogenic induction significantly affect ectopic bone formation, although such differences hardly affected the alkaline phosphatase activity or gene expression of osteogenic markers. Application of basic fibroblast growth factor helped to maintain the in vivo osteogenic ability of BMSCs. Importantly, responsiveness of those factors should be tested under clinical circumstances to improve the bone tissue engineering further. In this review, clinical application of bone tissue engineering was reviewed with putative underlying mechanisms.
