Tissue Engineering Using Stem Cells
Tissue engineering is a combination of biomedical science and engineering to regenerate cells, tissues, and organs. It encompasses a multidisciplinary approach toward the development of biological materials to restore and maintain normal functions in diseased or injured tissues. Compared to conventional therapy using drugs, tissue engineering is more effective because tissues with scaffold efficiently deliver cells and drugs. Tissue engineering includes three components including cells, biologically active factors, and biomaterials. Combination of these components enables the scaffolding for cell proliferation and differentiation, the isolation and culture of cells, the delivery system for nucleic acids and proteins. Development of these key technologies will assist and accelerate the regeneration of defective and damaged tissues.For successful regeneration of tissues or organs, it is important to develop appropriate biomaterials in their molecular design and creation of a local environment that enables stem cells to efficiently proliferate and differentiate. To enhance the proliferation of stem cells for tissue regeneration, biomaterial scaffolds for stem cells and the drug delivery system of growth factors have been investigated. Differentiation into diverse tissues using embryonic and adult stem cells are continually reported.
