Transplant research. Scientist performs a tensile strength test on a "tissue scaffold" sample used to grow artificial human organs for implantation. It contains a network of lactide or glycolide polymer fibres. Organs are made by placing a culture of cells from a patient's organ onto a shaped scaffold.Fed by special nutrients the cells multiply using the fibres as a scaffold to form an organ in a few weeks. Once implanted, the organ establishes a blood supply & the fibres break down into natural products which the body can dispose of. This technique eliminates the problems associated with transplants from donors. Photographed at Michigan University, USA.
