Midterm - Essay ExampleAdditionally, porosity allows waste products out of the scaffold.Biodegradability Since the intention of TE is to ease the bodys own cells to eventually replace the implanted meander engineered construct over time, scaffold are not intended to be aeonian implants. Thus scaffold need to be biodegradable to allow cells to generate their own extra-cellular matrix (Robert, 2013).The key consideration should be the source of the cells. Cells are categorise by their sources. For instance, autologous cells are obtained from the same individual to which they need to be re-implanted Allogenic cells are got from the body of the donor of the same species while xenogenic cells are from individuals of another species (Robert, 2013). During cells selection, cells hint to fewest problems with rejection and pathogen transmission are preferred (mostly autologous). However, autologous cells cannot be obtained if the individual affected is elderly or has suffered severe burn s.Biocompatibility The initial consideration of any biomaterial for TE is biocompatibility cells must stick, function normally and move onto the surface and finally through the biomaterial and begin proliferation process before producing new matrix. Biomaterial construct must show minimal immune reaction after implantation to prevent rejection by the bodyInjectability TE tissues requires precisely designed combination of cells and specialized scaffold support system, injectable biomaterials, especially those delivered in aqueous solution are ideal delivery vehicles for both the cells and bioactive factors (Robert, 2013).c) When designing a template for repairing a damaged bone, I lead ensure that the template is biodegradable, bioresorbable, three-dimensional which provides mechanical strength to the bone while at the same time providing a guide for regeneration of bone tissue (Robert. 2013). Thus the template
