The term has also been applied to efforts to perform specific biochemical functions using cells within an artificially-created support system (e.g . profiling of tumor tissue and plasma DNA with hybrid capture based NGS • Goal: perform molecular profiling on a recent biopsy and blood, convey results within 28 days. It may also be argued that tissue engineering could be associated with less risk than conventional medical devices or medicinal products, since the latter are mass-produced and the hazards related to defective products or unforeseen mechanisms can affect thousands of patients. Using nanotechnology, the properties of the materials can be manipulated according to our necessity. Tissue engineering replaces the diseased or damaged tissue or organs with biofabricated counterparts made using the specifications dictated by the features of the specific tissue or organ. 1. • Met interim analysis for futility, study stopped. Regenerative medicine focuses on the replacement and regeneration of tissues or organs. Although the method of decellularization seen in (A) provides a composite 3D structural scaffold, its constituents cannot be experimentally controlled preventing the method's reproducibility 3 .
