Biomaterial Properties
All bodily organs are susceptible to pathological conditions and age-related degeneration. Furthermore, the healing of large defects resulting from disease, trauma, infection or birth defects can be problematic and can often require a tissue graft for the reconstruction process
Traditional tissue engineering treatment options in reconstructive surgery include autografting and allografting to repair large defects. An autograft is considered to be the gold standard where by healthy tissue, harvested from the same patient, is moved from one place and implanted in another. Autografting is not associated with immune reaction or disease transmission risk and has excellent success rates. However, there are significant limitations including pain, limited availability of healthy tissue and increased surgical time. An allograft is healthy tissue harvested from a donor patient and implanted in the host patient,it is considered the most readily available graft. However, it has been associated with disease transmission, poor remodelling and a high probability of immune-rejection and inflammation. Xenografts are another option, in this case animal tissue is supplied as a powder, granules or blocks, but disease transmission and immune rejection are major risks.
