Scientists Help Bodies Grow New Organs

MELBOURNE, AUSTRALIA - JUNE 08: Research Assistant Effie Kermaidaris removes Cardiomyocytes tissue from a chamber at the Bernard O'Brien Institute of Microsurgery June 08, 2006 in Melbourne, Australia. The team of scientists and surgeons have developed a method of growing new organs within a patient's body. Cardiomyocytes and scaffold are seeded within the chamber into the groin of a rat. The construct is left for 4-6 weeks where the cells grow and form a 3 dimensional tissue construct with its own blood supply. This tissue has its own beating rhythm, which is different from that of the recipient. (Photo by Mark Dadswell/Getty Images)
