Frankenfish: Artificial jellyfish built from rat cells

Bio-physicist and -engineers from Harvard and Caltech have joined forces and created a swimming artificial jellyfish merely from rat cells. The jellyfish, or ‘medusoid’, is genetically rat with a silicone polymer ‘nerve system’ to control motion. The medusoid cannot eat, feel or reproduce, but mimics exactly the motion of the common jellyfish.

The researchers are normally occupied with ‘creating artificial models of human heart tissues for regenerating organs and testing drugs.’ They want to use the medusoid, or similar engineered ‘animals’, to test heart-drugs.¬†
