The expansion in clinical knowledge and the engineering quality of medical devices since the 1970s has led to substantial achievement. In spite of this accomplishment, however, the whole field of implant surgery is witnessing a gradual shift away from the healthy, maximally persistent approaches in the treatment of disorders and injuries towards the use of less persistent techniques. It is in this context tissue engineering and the development of tissue-engineered products has emerged. Regenerative medical therapy has been likely to pay off for the therapeutic disadvantages of reconstructive surgery and organ transplantation, as well as contributing a new curative strategy. The purpose of regenerative medical therapy is to provoke the repair of defective tissues based on the natural healing potential of patients. For flourishing tissue regeneration, it is vital to provide cells with a narrow environment of artificial extracellular matrix where they can proliferate and differentiate efficiently. Tissue engineering is the key to this renewal environment; release technology often enhances and prolongs the preservation of biological functions for tissue regeneration. Successful therapies resulting from regenerative medicine and tissue engineering technology may present new expectation for patients with organ failure, injuries or other clinical issues. At present, patients suffering from diseased and injured organs are treated with transplanted organs but there is a scarcity of donor organs that is worsening yearly as the population ages and new cases of organ failure enlarge. Researchers in the field of regenerative medicine and tissue engineering are now applying the principles of cell transplantation and bioengineering to construct biological replacements that can re-establish and preserve normal function in diseased and injured tissues. In addition, the stem cell field is a quickly escalating part of regenerative medicine, and recent discoveries in this field to create alternatives.
