Transplant research. Scientist makes materials used in tissue scaffolds to grow artificial human organs outside the body for implantation. Each tissue scaffold contains a network of lactide or glycolide polymer fibres. Organs are made by plac- ing a culture of cells from a patient's organ onto a shaped tissue scaffold. Fed by special nutrients the cells multiply using the fibres as a scaffold to form an organ in a few weeks. The implanted or- gan 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.
