Regenerative body parts in the works

A Canadian researcher is hoping that within ten years, people will be able to regrow tendons, spinal cords or heart valves lost to injury or disease. Dr. Brian Amsden, a chemical engineering professor from Queen’s University, is developing a technique wherein cells from a patient’s body would be placed on a polymer prosthetic that stimulates cell growth. After the cells had established themselves sufficiently, the prosthetic would be implanted in the patient’s body. The polymer would then biodegrade, leaving behind nothing but the patient’s own tissue.
