Question:
What has been achieved so far and what challenges need to be surmounted?
▶️Answer/Explanation
Ans: Achievements so far include:
• Production of a variety of suitable biomaterials;
• Successful use of biomaterials to act as a scaffold for a new tissue/organ;
• Getting many cell types to grow outside the body;
• Using stem cells to produce functioning tissues such as cardiac muscle;
• Production of bladders for transplant using a patient’s own stem cells;
• Development of printing technology in which cells are applied in layers, in precise arrays as in natural organs;
• Development of techniques for wound healing by applying cells with printing technology to a wound on a patient.
Challenges still to be surmounted include:
• Producing solid organs such as kidneys;
• Getting liver, nerve and pancreas cells to grow outside the body.
