It looks like a jellyfish, it acts like a jellyfish — but genetically it’s a rat.
A team of scientists at Harvard University built this jellyfish using cells from the heart of a rat. Just like a natural Moon jellyfish, this creation can pulse and move when exposed to an electric current, according to Gizmodo.
The experiment was published in Nature Biotechnology.
Lead researcher Kit Parker’s work revolves around “creating artificial models of human heart tissues for regenerating organs and testing drugs, and the team built the medusoid as a way of understanding the ‘fundamental laws of muscular pumps,’” he said in Nature.
Parker was searching for a new way of studying muscular pumps when he visited the New England Aquarium in Boston, Massachusetts and saw the jellyfish. “I thought: ‘I know I can build that,’” he said.
A team of bioengineers and graduate students took the rat apart and made a jellyfish. “Usually when we talk about synthetic life forms, somebody will take a living cell and put new genes in. We built an animal. It’s not just about genes, but about morphology and function,” Parker told Nature.
The team hope to use the jellyfish, and other animals made from heart tissue, to test heart medications. What do you make of this experiment? Tell us in the comments.
